Volodymyr Zelensky finds himself in an impossible bind: risk Donald Trump's wrath or accept a quick deal to end Russia's war in Ukraine by paying the disastrous price of ceding territory for vague security guarantees.

Trump will meet the Ukrainian leader, along with several European heads of state and the NATO Secretary-General, on Monday.

The coalition of the willing, the alliance which is planning to police a future peace deal, will meet on Sunday afternoon.

European leaders will join Ukraine's Zelenskyy for a meeting in Washington days after Donald Trump's summit with Russia's Putin in Alaska.

The planned summit between U.S. President Donald Trump and Russian leader Vladimir Putin is a "highly anticipated meeting," the Republican said.
