Russia must be held accountable over Ukraine – we should seize its assets | Joseph Stiglitz and Andrew Kosenko

After the EU and US failed to agree aid packages, we must send a clear message to regimes waging wars

As Russia's war against Ukraine continues to wreak havoc regionally and globally, the Ukrainian people and their allies demonstrate remarkable determination and courage. But almost two years after Russia launched its full-scale invasion, it is increasingly clear that the international community can and must do much more to help.

While the G7 countries and other governments around the world have been extraordinarily generous in supporting the Ukrainian war effort, there are signs of growing fatigue in some circles - a development Russia appears to have anticipated. With the US and the EU failing to commit more than $100bn (80bn) in aid to Ukraine in December, the idea of seizing Russian assets frozen by western countries has re-emerged as a potential solution.
