“Moscow’s economy has declined, but Russia’s sales of commodities will keep Vladimir Putin’s regime supplied with the necessities of war for a long time.

Kyiv cannot export most of its harvest to earn foreign currency. The best guesses are that Ukraine needs between $5 billion and $6 billion in assistance each month just to stay afloat. Nevertheless, heroic Ukrainians have managed to maintain basic governmental functions while supporting an army at war.”
