How has the Trump administration's recent negotiation stance on Ukraine affected NATO's objectives and Ukraine's position?

The Trump administration has undermined NATO's longstanding objectives by abandoning the goal of restoring Ukraine's territorial integrity and sovereignty, which has been NATO's position since Russia's 2022 invasion. According to John Bolton, Trump has given away key negotiating points before negotiations even began, including removing the prospect of NATO membership for Ukraine. These concessions were made without securing any reciprocity from Russia. By yielding to fundamental Russian demands despite their battlefield defeats, Trump has placed Russia in a significantly stronger bargaining position, weakening Ukraine's sovereignty and long-term prospects.
