What are the major concerns with Trump's negotiation approach toward Russia and Ukraine, and why are European and Ukrainian leaders shocked by his tactics?

European leaders and Ukrainian officials are in shock over Trump's negotiation strategy because he gave Putin significant concessions before negotiations even began. According to former Ambassador McFaul, Trump publicly stated that Ukraine cannot join NATO, must give up territory, and that American troops won't participate in peacekeeping - essentially offering everything Russia wanted upfront. This approach is strategically flawed because, as McFaul explains from his experience negotiating with Russians, when you give them something, "they're going to put it in their pocket and ask for more." The strategy is being compared to Neville Chamberlain's appeasement policy, suggesting it could encourage further Russian aggression. The concern extends beyond tactics to moral implications, as this approach abandons Ukrainian allies who are fighting for their sovereignty while potentially emboldening Putin's territorial ambitions.
