European and Ukrainian officials are concerned that Donald Trump may abandon peace negotiations between Kyiv and Moscow, potentially using minor progress as a reason to disengage. Despite his promise to end the war quickly, Trump has struggled to gain support for a ceasefire amid Putin’s refusal to meet key demands, prompting worries that he is preparing to leave the resolution efforts to Ukraine and Europe. As tensions rise, Kyiv is reportedly preparing for a possible reduction in US support by bolstering domestic arms production and seeking further assistance from European allies.
