"If Russia occupies all of Ukraine, who knows?" he replies. "In 10 or 15 years' time, Russia will go to Poland, Lithuania, Estonia, any of the Baltic countries, that is quite clear."
US military aid for Ukraine is gradually going to run out. No more packages are going to be put before Congress or unlocked by presidential draw-down powers.
Should Washington turn its back on these peace efforts, it would leave Ukraine reliant on its European allies to counter Russia's continued invasion. The consensus is that that collective weight would be insufficient in the long term.
