The hope of a U.S.-brokered peace deal between Russia and Ukraine has been dashed, at least temporarily, with the public breakdown Friday of talks between President Donald Trump and Ukrainian President Volodymyr Zelensky in the White House.

The original plan had been for the United States and Ukraine to sign an economic agreement as a precursor to continued U.S. support and a potential peace deal, with a table set up in the East Room for a press conference and the signing, but the Oval Office exchange between the men changed everything.
