> The US, especially, seems to by trying to help Ukraine win, but not win so hard that Russia collapses, and it's not obvious that a level of support exists that would satisfy both outcomes I've always thought the US wanted Ukraine not to lose. Tying up Russia's armed forces in an endless war of attrition seems like an ideal result on all grounds except humanitarian ones. European countries have slightly different incentives because they would also like to stop the refugee crisis, but the US is basically the marginal supplier of arms here - if Estonia finds it can lend another 5 fighter jets, the US can just provide 5 fewer.
