there are reasonable policies between "give ukraine everything she possibly wants to protract a war of attrition that risks backing a nuclear power into a corner" and "tell ukraine to pound sand and kiss putin's ring."

for instance, EU states were repeatedly warned about their reliance on russian energy. the EU preferred to empower putin and constrain future actions in exchange for cheap power. perhaps, rather than passing the next massive aid bill, the EU could focus hurting the aggressor state by literally just not sending her more money on a regular basis. that'd be a great first place to start.

or perhaps EU states could have gotten their act together faster and sent more than busted old helmets (cough Germany cough). trump says a lot of dumb stuff but he's entirely correct that europe has repeatedly failed to adequately invest in her own defense, in light of the fact that she has an aggressive, expansionist would-be-again superpower on her eastern border. then when America doesn't pony up what europe thinks is enough, she goes on a whining tour and asks why the evil Americans won't spend enough money and lives to fight fascism.
