When President Donald Trump won last year’s election, European officials quickly began discussing how to sustain US weapons shipments to Ukraine under a leader who had vowed to pull back American support.

Trump's moves underline his growing disenchantment with Russian President Vladimir Putin over the lack of progress in U.S.-led efforts to secure a ceasefire.
