How do Trump's recent positions on Ukraine and NATO affect Russia's negotiating position?

According to John Bolton, Trump's recent positions have put Russia in a very strong negotiating position. By abandoning NATO's fundamental objective of restoring Ukraine's territorial integrity and sovereignty, and taking NATO membership for Ukraine off the table before negotiations even begin, Trump has conceded major points to Russia without receiving any concessions in return. Bolton emphasizes that these unilateral concessions strengthen Putin's hand in future negotiations, especially concerning Ukraine's future, despite Russia's battlefield struggles. This approach effectively undermines longstanding U.S. and NATO policy positions that date back to 2008.
