Donald Trump’s remarks on Ukraine on Monday were far from the biggest announcement the US president could have made.

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.

Trump also revealed that Putin had recently offered to assist in mediating between Israel and Iran during their brief June conflict — an offer he declined. “I said, ‘No, no, you help me get a settlement with you, with Russia,’” Trump recounted. “And I think we're going to be doing that too.”
