In a few short weeks, on Feb. 24, the world will mark the fourth anniversary of Russia’s full-scale invasion of Ukraine. It’s been a long four years, with total combined military casualties — including killed, missing and wounded — estimated at between 1.8 million and 2 million. Those numbers include some 275,000 to 325,000 Russian military deaths, 100,000 to 140,000 Ukrainian military deaths and more than 14,000 verified Ukrainian civilian deaths.

This is not a Russian or Ukrainian or European tragedy. It is a global tragedy.

Countries condemning Russia’s military actions have imposed and strengthened financial and economic sanctions against Moscow. Yet the war has lasted far longer than initially assumed and international attention and policy debates have increasingly spread to other geopolitical crises, including those in the Indo-Pacific. Against this backdrop, renewed attention must be paid to the reality of burden-sharing among advanced economies in supporting Ukraine, including who has contributed, in what form and to what extent.
