Vice President JD Vance cautioned Ukrainian President Volodymyr Zelensky against making disparaging comments about President Donald Trump and warned that it would "backfire" on him.

The idea that Zelensky is going to change the president’s mind by badmouthing him in public media, everyone who knows the president will tell you that is an atrocious way to deal with

Zelensky was widely viewed in America as a Churchillian hero for putting up a surprisingly stubborn resistance to Putin’s 2022 invasion, reportedly brushing off an offer of a flight out of the country from then-President Joe Biden with the quip, “I need ammunition, not a ride.”

After Trump called Zelensky a “dictator” and began talks with Russia, even some of Zelensky’s harshest domestic critics have begun defending him.

President Donald Trump’s promotion of Russia’s narrative has caused worry in Europe that the United States is redrawing its longstanding alliances.
