President Donald Trump’s suggestion that Ukraine should recognize Russia’s control over Crimea, the southern Ukrainian peninsula Moscow siezed by force more than a decade ago, is threatening to upend international law and order.

A new U.S. peace plan offered to Russia and Ukraine proposes American recognition of the peninsula, which Moscow seized in 2014.

President Donald Trump, who CNN reported Friday has been surprised and frustrated at the difficulty of achieving his promise of ending the war, wants Ukraine to give up territory in exchange for peace and essentially cede control of Crimea, the peninsula Russia first invaded in 2014.

President Donald Trump said Saturday that he is beginning to question whether Russian President Vladimir Putin wants to end the Russia-Ukraine war, a warning shot to the Russian leader that came just after Trump met with Ukrainian President Volodymyr Zelenskyy in Rome.

President Trump said Saturday that he doubts Russia’s Vladimir Putin wants to end his war in Ukraine. Only a day earlier, Trump said Ukraine and Russia were " very close to a deal."

Like many American leaders before him, US President Donald Trump is finding out that getting through to Russian President Vladimir Putin is not as easy as he might have thought.

Trump's envoy Steve Witkoff met President Vladimir Putin in Moscow in what Trump has called a key moment in diplomacy to end the war in Ukraine.
