President Donald Trump framed his Friday summit with Vladimir Putin as a moment to feel out the Russian leader’s parameters for ending the war in Ukraine and acknowledged it would take further meetings to strike a final peace deal.

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.

Trump has appeared increasingly exasperated over Russia’s refusal to halt the bombardment of Ukrainian cities.
