Ukraine: the battle for Donbas will be protracted and bloody – military expert

There will be no peace deals, no ceasefires and no surrenders in Ukraine. The next two months will bring what US defence officials have called “a knife fight” in the area the Ukrainian army call “The Joint Forces Operation” (JFO). We know this region better as Donbas.

For eight years the two sides have fought there, with Russian regular army elements supplementing separatist units. Now, after defeat in Kyiv, Russian forces are redeploying there to take on Ukraine’s best and most experienced units. The battles to come will resemble more the manoeuvre battles of the second world war than those fought around the cities of Kyiv, Mariupol and Sumy in the six weeks the war has raged so far. Nonetheless, the Russians are unlikely to prevail.

After their recent defeat in the north, Russia has made some significant changes. Most importantly, an overall commander has been appointed. The importance of this is not the identity or experience of the individual Colonel General Alexander Dvornikov – rather it is the fact that the Russians will have a single command staff to co-ordinate and attempt to achieve a single focused and ostensibly realistic operational objective, instead of three separate competing ones in the north, south and east.

Russia is desperately trying to replace its considerable losses, up to 20% of its force already. Those efforts will make little difference. The conscript troops and reactivated reserves called up recently will not be ready for months. Nonetheless the force the Russians will amass will be formidable, and with shorter and better established supply lines into Russia they may be able to avoid some of the appalling foul ups which have characterised their war so far.

Equally importantly, in theory, they should be able to use their air force to greater effect, being closer to its bases and air defence cover. But recent events have shown that theory is a poor guide to what the Ukrainian air defences can achieve. Finally, the Russian army has always been and remains very strong in artillery, the arm they call “the Red God of War”.

Battles in bulges

These forces are pitched against Ukrainian defenders deployed in several salients or “bulges” – areas surrounded on three sides by Russian-backed separatists. Throughout military history these have offered the possibility of trapping enemy forces in “pockets”. Military historians will recall the Ypres Salient (1914-1918), Verdun (1916), Kursk (1943) and of course the Battle of the Bulge (1944-45) as the most prominent examples of this.

The Russians will seek to probe and break through Ukrainian defences, surround those salients, trap the Ukrainians and annihilate them using their advantages in air and artillery power, or at the very least force them to retreat. Russian-backed separatist troops successfully conducted such an operation on a relatively small scale at the Battle of Debaltseve in February 2015, where artillery was used to devastating effect.

US military analysts report they expect Ukrainian positions in the Severodonetsk Salient, and especially around the town of Sloviansk to be the initial targets for a Russian attempt at encirclement, with an eventual strike at the city of Dnipro – a major communications and road hub – to secure the entire region east of the Dneieper River. All of this this is very well known by the Ukrainian commander, General Valerii Zaluzhnyi and his staff. The Russians want quick battles of annihilation. What they will get is a war of attrition.

Ukrainian commanders fully and completely understand from bitter experience the risks of being surrounded. They have demonstrated the qualities of agility and tactical innovation required for this kind of battle. Even better, they know what is coming. Nato air and space reconnaissance and surveillance as well as Ukraine’s own intelligence capabilities will ensure that there will be no surprise attacks.

Long war?

With continued and increased western assistance, Ukraine should be able to sustain a long war better than the Russians. Nato assistance will be vital in firming up the defenders’ armoured units giving them a far greater chance to counterattack and retake ground. Retaining some level of control of the air, though, is the single most important factor, which is why retaining and strengthening anti-aircraft missile defences is an absolute priority.

Despite Russia’s advantages in technology and equipment, Ukrainian forces will continue to exploit Russia’s chronic and acute weaknesses in logistics and supply.

Finally, it is one of the firmest rules of warfare that a successful attacker should enjoy a three-to-one preponderance. Russia’s depleted force has nowhere near that preponderance. There are exceptions to this general three-to-one rule – such as the Gulf War of 1991 where a well-led and equipped US-led coalition annihilated a larger and combat-experienced Iraqi army. In such cases, the attackers more than made up for a relative lack of quantity with quality in training, planning and the crucial moral components of cohesion and motivation.

In the spring battles of 2022 it is the defenders, not the attackers who are in abundant possession of those factors against a Russian army beset by chronic issues of endemic corruption professionalism and training which has rendered them apparently incapable of conducting complex operations. These problems are not going away, and will not be solved by a change in command or operational focus.

Above all the ravages inflicted upon them by the Ukrainian armed forces have cut away at their manpower, equipment and morale. The next battle will begin within the next two weeks. Attempting to predict its precise course is ultimately futile, not even the opposing generals know that. It may well be that the Russian army’s fate has already been sealed in what is likely to be a long war.

The single qualification to this may be that Russia could default to escalation using “weapons of mass destruction” of one form or another – whether tactical nuclear warheads or chemical weapons. Reports from Mariupol that the Russians may already have resorted to the latter would, if proved, show that Russia is prepared to resort to something even more serious if they fear a complete military humiliation in Ukraine.

EXTRACT: "But even a resounding Russian defeat is an ominous scenario. Yes, under such circumstances – and only such circumstances – Putin might be toppled in some kind of coup led by elements of Russia’s security apparatus. But the chances that this would produce a liberal democratic Russia that abandons Putin’s grand strategic designs are slim. More likely, Russia would be a rogue nuclear superpower ruled by military coup-makers with revanchist impulses. Germany after World War I comes to mind."

EXTRACT: "For citizens of states that are members of NATO, taking all possible steps, short of all-out war, to ensure that Russia does not conquer Ukraine is not even an altruistic sacrifice. It is a long-term investment, for themselves and their children, in freedom, democracy, and the international rule of law."
May 4th 2022
EXTRACT: ".....a remarkable transformation is taking place in Ukraine’s army amounting to its de facto military integration into Nato. As western equipment filters through to the frontline, Nato-standard weaponry and ammunition will be brought into Ukrainian service. This is of far higher quality than the mainly former Soviet weapons with which the Ukrainians have fought so capably. The longer this process continues and deepens, the worse the situation will be for the already inefficient Russian army and air force."

EXTRACT: " The conventional wisdom among students of the Russian arts and sciences is that Russian culture is “great.” The problem is that, while there are surely great individuals within Russian culture, the culture as a whole cannot avoid responsibility for Putin and his regime’s crimes." ---- "Russianists will not be able to avoid examining themselves and their Russian cultural icons for harbingers of the present catastrophe. What does it mean that Fyodor Dostoevsky was a Russian chauvinist? That Nikolai Gogol and Anton Chekhov were Ukrainian? That Aleksandr Solzhenitsyn was an unvarnished imperialist? That Aleksandr Pushkin was a troubadour of Russian imperial greatness? May these writers still be read without one eye on the ongoing atrocities in Ukraine?"

EXTRACT: "The following day Lavrov met his Eritrean counterpart, Osman Saleh, in Moscow. Eritrea was the only African country to vote against the UN resolution condemning the invasion. In this refusal to condemn Russia, Eritrea was joined by only Belarus, North Korea and Syria. Even longstanding allies such as Cuba and China abstained. It’s an indication of Russia’s increasingly limited diplomatic options as this war continues."

EXTRACT: "Although the milestone lasted only for a brief time, it points to a future in which California runs on 100% wind, solar, hydro and batteries, a future that will certainly arrive even faster than the state plans. As it is, California is ahead of its green energy goals." ...... "A world of 100% green energy and electric cars is not only a healthier and more comfortable world, it is a world where oil and gas dictators like Vladimir Putin are defunded."

EXTRACT: "Kazakhstan’s authorities have also showed uncharacteristic leniency in allowing public rallies in support of Ukraine. Thousands of protesters holding banners reading “Russians, leave Ukraine”, “Long Live Ukraine” and “Bring Putin to trial” marched across the capital, Almaty, wrapping monuments to Lenin and other Soviet-era figures with yellow and blue balloons symbolising the Ukrainian flag."
Apr 15th 2022
EXTRACT: "People’s identification with the Soviet Union appears to have a clear and growing basis in Russian public opinion. Surveys we have conducted throughout the Putin period show that Soviet identification among the general population – something that had been steadily declining after the collapse of the Soviet Union in 1991 – began to increase in 2014, when the Russian government annexed Crimea and supported rebellions in the Ukrainian regions of Luhansk and Donetsk. By 2021, almost 50% of those surveyed identified with the Soviet Union rather than the Russian Federation."

EXTRACT: "Worse yet, the Hungarian government has effectively been helping Putin by prohibiting the shipment of weapons to Ukraine across its borders. Hungarian public TV spreads Russian disinformation day and night. The day before the election, an assembly of ordinary people expressing solidarity with Ukraine was framed on state television as a “pro-war rally.” "

EXTRACTS" "Ukraine and Russia produce a substantial amount of grain and other food for export. Ukraine alone produces a whopping 6% of all food calories traded in the international market. At least it used to, before it was invaded by the world’s largest nuclear power." ...... "When it comes to cereals like wheat, corn, rice and barley, the big players talk about millions of metric tonnes, or MMTs. A single MMT of wheat contains about 3.4 trillion food calories,." ....."Ukraine produced about 80 MMT of grain (a category that includes wheat, corn and barley) in 2021, and is expected to harvest less than half of that this year. A shortfall of 40 MMT is enough missing calories that a country like the UK could only make it up by having everyone stop eating for three years. That’s the thing about tonnes of grain: a million here and a million there and pretty soon you’ve got a real issue on your plate."

EXTRACT: "I don’t even know the little girl’s name. All I do know is what a friend of a friend wrote on Viber: that her relative, a senior nurse in one of Kyiv’s hospitals, “saw in the morgue a child with 20 varieties of sperm on her small body.” Since this information was conveyed in a private conversation, there is no reason to doubt its veracity."
Apr 8th 2022
EXTRACT: "Russian society has so far failed to stop Putin, just as German society failed to stop Hitler. And so, like a poisoned chalice, that task has fallen to the West, as it did in 1939. The West must now treat Putin and his regime the same way that Winston Churchill treated Hitler: Don’t talk to him, just defeat him. Dead-enders such as Putin are too fanatical and desperate to be reliable negotiating partners."
Apr 3rd 2022
EXTRACT: "From 1807 to 1814 on the Iberian peninsula, Napoleon had to fight Spanish, Portuguese and British armies while beset by ubiquitous, ferocious insurgents. He described this war as his “bleeding ulcer”, draining him of men and equipment. It is the west’s aim to make Ukraine for Putin what Spain was for Napoleon. In the absence of a negotiated settlement, Ukraine and Nato will continue to grind away at Russia’s army, digging away at that bleeding ulcer and prolonging Russia’s agony on the military front, as the west continues its parallel assault on its economy. If Putin’s plan is to proceed with the Korea model, he will fail. There is a strong possibility that Putin has only a limited idea of how badly his army is faring. So be it – he’ll find out soon enough that there is now no path for him to military victory."

EXTRACTS: "Policymakers expected that the country would be able to secure its energy supply entirely from renewable sources, so they resolved to phase out coal and nuclear energy simultaneously. The last three of Germany’s 17 nuclear power plants are set to be shut down this year." ---- ".... the share of wind and solar power in Germany’s total final energy consumption, which includes heating, industrial processing, and traffic, was a meager 6.7%. And while wind and solar generated 29% of the country’s electricity output, electricity itself accounted for only about a fifth of its final energy consumption." ----- "If Germany suddenly halted Russian gas imports, gas-based residential heating systems – on which half the German population, approximately 40 million people, rely – and industrial processes that rely heavily on gas imports would break down....."
Apr 1st 2022
EXTRACT: "For Putin, the past that matters most is the one the dissident author and Nobel laureate Aleksandr Solzhenitsyn exalted: the time when the Slavic peoples were united within the Orthodox Christian kingdom of Kievan Rus’. Kyiv formed its heart, making Ukraine central to Putin’s pan-Slavic vision. ---- But, for Putin, the Ukraine war is about preserving Russia, not just expanding it. As Russian Foreign Minister Sergei Lavrov recently made clear, Russia’s leaders believe that their country is locked in a “life-and-death battle to exist on the world’s geopolitical map.” That worldview reflects Putin’s longstanding obsession with works of other Russian emigrant philosophers, such as Ivan Ilyin and Nikolai Berdyaev, who described a struggle for the Eurasian (Russian) soul against the Atlanticists (the West) who would destroy it. ---- Yet Putin and his neo-Eurasianists seem to believe that the key to victory is to create the kind of regime those anti-Bolshevik philosophers most detested: one run by the security forces. A police state would fulfill the vision of another of Putin’s heroes: the KGB chief turned Soviet General Secretary Yuri Andropov."

EXTRACTS: "Ukraine, known as the breadbasket of Europe, is struggling to export last year’s harvest, and may be unable to produce much this year either. In addition, the war has caused a global fertiliser shortage, which will push up food prices around the world too. Coming at a time when the global pandemic had already increased food insecurity and depleted resources around the world, many countries may not be resilient to a major food crisis brought on by the war. Back-to-back global catastrophic events like this have not happened for close to 100 years." ----- "Another useful analogue is the case of Germany during the first world war. When war broke out in 1914, the German authorities had anticipated a short conflict – not too dissimilar to Russian assumptions a few weeks ago. Just like in Ukraine now, the first world war severely disrupted German farming."
Mar 31st 2022
EXTRACT: "The horrors of World War II – the death camps, slave labor, and inhumane experiments on people – produced a global commitment never to permit such crimes to be repeated. This began a transformation of international politics whereby appreciation of the value of every person’s life and dignity ensured that even most authoritarian governments at least paid lip service to human rights.  ----- But the Soviet Union and many of its successor states, particularly Russia, never internalized this change. More than three decades after the USSR collapsed, most post-Soviet countries are still governed according to the old “imperial” paradigm. So, it should come as no surprise that we are now witnessing a clash between fundamentally different sets of values and ultimate goals for statehood."
Mar 26th 2022
EXTRACT: "Referencing past legacies as a justification for present-day political decisions is often effective – such appeals trigger emotional reflexes and contribute to thinking about politics in terms of rivalry and defence. The irony within the tragedy of the current situation is that Putin will assuredly go down in history as the figure that did more to unite the Ukrainian people (albeit against Russia) than any other in recent memory."
Mar 24th 2022
EXTRACT: " Despite the death and destruction that Russia rains down daily on them, the vast majority of Ukrainians are bullish about the future: 77% believe the country is moving in the right direction, 93% think they can beat back Russia, and 47% expect to win in the next few weeks.  Ukrainian policymakers are no less bullish, driving a hard bargain in negotiations with the Russians. Several factors account for this remarkable optimism."
