At least four times in the past week, the Trump administration has linked financial support for the United Nations to compliance with American demands.

First President Trump and his ambassador, Nikki R. Haley, fumed that all countries with seats on the Security Council except the United States had opposed American recognition of Jerusalem as Israel’s capital and his decision to put the United States Embassy there.

Then Mr. Trump dared the General Assembly to follow the Security Council’s example. “Let them vote against us,” he said. “We will save a lot.”

When the General Assembly voted 128 to 9 against the Americans, Ms. Haley said she would take names and remember them the next time the United States was asked for financial help from members who disagreed with its stance on Jerusalem.
