Ukrainian President Volodymyr Zelenskyy's heated exchange with U.S. President Donald Trump has Russian leaders reveling in the spectacle, with one saying Kyiv got a "slap down."

If the Europeans were in shock when they saw that unprecedented on-camera moment at the White House play out, the Russians were jumping with glee. Even after Trump incorrectly labeled Zelenskyy as a "dictator" last week, the Kremlin could never have imagined today's meeting would have panned out so well, in their favor.
