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.

US President Donald Trump has announced the US will send "top-of-the-line weapons" to Ukraine via Nato countries, while also threatening Russia with severe tariffs if a deal to end the war is not reached within 50 days.
