What concerns do European leaders have about Trump's negotiation strategy for the Ukraine-Russia conflict?

European leaders, particularly Emmanuel Macron, express deep concern that the Trump administration's approach of rushing into a quick deal with Putin could lead to a repeat of the failed Minsk agreement from 2014. The Minsk agreement, which attempted to stop fighting in eastern Ukraine after Russia's first invasion, was ultimately a disaster that allowed Russia to buy time before launching a full invasion. There are fears that a hastily negotiated settlement would result in another stalled, paused, or frozen conflict that might only temporarily halt hostilities. European leaders worry this approach could lead to a renewal of war in the months or years to come rather than establishing a sustainable peace for Ukraine.
