As we mark the second anniversary of Russia's full-scale invasion of Ukraine, we consider the implications of what has turned into a protracted conflict.

Russia has seized back the initiative in the war, due at least partly to ampler supplies of ammunition and drones. While Ukraine continues to achieve important tactical victories against the Russian Black Sea Fleet, the land and air campaign is increasingly characterised by Russian pressure and territorial gains.

There are also growing doubts about the ability of the Euro-Atlantic community to adequately resource the war, with acute concern about the deadlocked debate in the US Congress over military support for Ukraine.

As we enter the third year of the war, it is likely the fighting will stretch well into the future.

Where is the war heading? And can Western unity on Ukraine hold?
