A meeting between Ukrainian President Zelenskyy and President Donald Trump exploded after Zelenskyy rejected a deal that did not include security guarantees for his country.

It was an astonishing display of open antagonism in the Oval Office, a setting better known for somber diplomacy. Trump laid bare his efforts to coerce Zelenskyy to agree to giving the U.S. an interest in his country’s valuable minerals and to push him toward a diplomatic resolution to the war on the American leader’s terms.
