U.S. President Donald Trump told President Volodymyr Zelenskiy on Monday that the United States would help guarantee Ukraine's security in any deal to end Russia's war there, though the extent of any assistance was not immediately clear.

After witnessing the red carpet rolled out for Russian President Vladimir Putin last Friday; the jet flyover; the ride in the presidential limousine, many Ukrainians feared the American president’s bromance with the wily old KGB agent had reignited.

Geraldo Rivera praised President Donald Trump on Newsmax Monday for his diplomatic efforts to end the war between Russia and Ukraine. Ukrainian President Volodymyr Zelenskyy met with Trump in the Oval Office just three days after Trump’s Alaska summit with Russian President Vladimir Putin and several months after their tense February encounter.

President Trump has offered only vague assurances of security guarantees for Ukraine if President Volodymyr Zelensky agrees to cut a deal with Russia.

As Trump was flying into Alaska, he was threatening severe consequences if Putin didn’t play ball. Trump stressed that he wouldn’t be happy if he left the summit without an immediate ceasefire and that new sanctions may be necessary if the Russians were intransigent.

The US president said a peace agreement would be better than a "mere" ceasefire, hours after summit with Putin that produced little.

With no strategy of their own for ending the war, the continent’s leaders are anxious that President Trump will force Kyiv to accept terms that favor Russia too much.
