Is the war slipping away from Ukraine?

After the decisive failure of Russia’s attempt to overthrow the government of Ukraine by seizing Kyiv, Kharkiv and other key cities in February and March 2022, Russia has concentrated its depleted forces in the Donbas and set itself far more limited objectives. In the two months since its retreat from the north of Ukraine, Russia has finally subdued the besieged defenders of Mariupol – who had been surrounded since the second day of the invasion – and slowly gained territory in Donbas. Since then Russia’s most notable conquest has been the small but important town of Popasna and the surrounding high ground that overlooks key supply routes into the city of Sievierodonetsk. Russia is slowly inching forward in Donbas, but its progress needs to be understood as part of the wider context of the war as a whole.

Inside Russia’s military collapse in Ukraine

The Russian military has performed far worse in Ukraine than anyone could ever have predicted. After failing to take Kyiv, Russian troops have now been forced to focus on the Donbas region. Despite this greater concentration of forces, they are still struggling to make any major gains beyond the final capture of Mariupol, which had been under siege since the first days of the invasion without resupply or relief. For Vladimir Putin this represents a grand humiliation. But for the West, Russia’s struggling campaign offers an unrivalled opportunity to understand Russia’s capacity to pose a future military threat. Key to this will be working out how many of Russia’s current failings are down to the specific circumstances in Ukraine, and how many are due to systemic problems within the Russian military itself.

Russia and Ukraine’s fate is about to be decided

The first phase of the Russian invasion of Ukraine has ended with a decisive defeat for Russian forces in the north of the country. The large scale Russian advances in the north west and north east were halted in the outskirts of Kyiv. Russian forces failed to take the encircled north eastern cities of Chernihiv, Sumy and Kharkiv and have subsequently been forced to withdraw to their starting positions in Belarus and Russia itself. The discovery of horrific Russian atrocities committed against the Ukrainian civilian population in the newly liberated towns has hardened Ukrainian determination to take back all of their lost territory rather than accept any ceasefire along current lines. In determining the outcome of this war, the next fortnight is likely to prove crucial.

Why Russian tactics won’t win the war

As the Russian invasion of Ukraine enters its second month, the war has settled into a largely attritional struggle – and the picture is very different across the various fronts. Russian forces have been forced on to the defensive in many areas. The Russian ministry of defence has announced that the ‘first phase’ of the invasion is over, to be replaced with a more limited focus on Donbas in the east of Ukraine. The reason for this is simple: Ukrainian forces have not only stopped the Russian advances around Kyiv in the north and Mykolaiv in the south-west but have begun to regain towns and cut key Russian supply routes. In the Donbas region in the east, however, Russian and separatist forces continue to make slow, costly progress in repeated assaults along the Donets river defence line.

The Russian army is running out of momentum

As the Russian invasion enters its fourth week it is clear that its forces are running out of momentum, although they continue to make limited territorial gains in the south and east of Ukraine. Having been denied a quick victory over Ukraine itself, Putin now needs to force the Ukrainian government to accept a ceasefire agreement that largely freezes the frontlines and allows him to claim a victory domestically. His strategy now appears to be to cut off the Ukrainian forces fighting a desperate battle to hold the line in Donbas in the east against combined Russian and separatist Donetsk and Luhansk forces from the rest of Ukraine, and to concentrate more firepower on the besieged cities of Mariupol in the south and Kharkiv, Sumy and Chernihiv in the north.

Why hasn’t Russia been able to stop Ukraine’s drone attacks?

Among the many weapons being used by the Ukrainian military to inflict losses on the Russian invasion forces, several have risen to prominence in the country and on social media. Alongside ‘St Javelin’ and the ‘Ghost of Kiev’ which have mythologised the eponymous anti-tank missile and the Ukrainian air force’s Mig-29 fighters, the Bayraktar TB-2 unmanned aerial vehicle (UAV) has gained a symbolic place in the Ukrainian defensive arsenal. The TB-2 is a relatively small medium-altitude long endurance class drone. It weighs around half a ton, cruises at 70 knots (80 mph), and can carry up to four small laser-guided bombs with a practical engagement range of around 8km. Despite its unassuming size and payload, the TB-2 has risen to prominence by destroying significant numbers of armoured vehicles and short-range air defence systems in Syria, Libya, Nagorno-Karabakh and now most recently in Ukraine.

Putin’s dream of annexing Ukraine is over

As the Russian invasion of Ukraine enters its third week, it is becoming abundantly clear that the Kremlin’s maximalist geopolitical aims of regime change and a ‘greater Russia’ which includes Ukraine and Belarus are no longer achievable. The question now is how much damage will Russian forces inflict on Ukrainian cities and their brave defenders before Putin and his advisors lower their ceasefire conditions to terms that Ukraine’s leaders and population can accept. Ukraine is in a strategically stronger position than many in the West appreciate, but the war on the ground is still stacked in Moscow’s favour in the short term. The plan to decapitate the Ukrainian state at the national and local levels with infiltrated special forces and operatives, while seizing key points with airborne assaults and surrounding the major cities with ground forces, failed spectacularly during the first week.

The Russian army is failing – but not enough to lose the war

There have been three major surprises for military analysts since the Russian military invaded Ukraine. The first has been the extent of the difficulties faced by the Russian army in terms of logistics, coordination of forces, morale and mobility. The second has been the failure of the Russian air force to achieve air superiority over Ukrainian air defences, and to operate against Ukrainian ground forces at scale. The third has been the extraordinary unity and effectiveness of the Ukrainian resistance, which has significantly slowed the Russian advance in the north of Ukraine and inflicted major personnel and vehicle losses on Russian forces on all fronts. Unfortunately, none of these factors change the overall prognosis that a military victory for Russia during the conventional combat phase of this war is very likely.
