President Donald Trump on Monday previewed his highly-anticipated meeting with Russia's Vladimir Putin, saying he's hopeful for "constructive conversations" but that it isn't up to him to make a peace deal.

The threats, pressure and ultimatums have come and gone, but Russian President Vladimir Putin has maintained Moscow’s uncompromising demands in Ukraine, raising fears he could use a planned summit with U.

It took Ukraine’s president time and effort to not only repair his diplomatic relations with the Trump administration, but also to prove that no one wants the end of Russia’s all-out war more than Ukraine does.
