It is clear from President-elect Donald Trump’s choices for his new administration, from the chief of staff to border czar to U.S. ambassadors to the U.N. and Israel, that he means to hit the ground running on Inauguration Day.

We hope that when it comes to the U.N. Relief and Works Agency for Palestine Refugees, Mr. Trump will immediately defund an agency that serves as an ATM for Hamas teachers whose facilities above and below ground have been used as jumping-off points to murder and maim innocents and whose pedagogical raison d’etre is to brainwash Palestinian children to seek Israel’s destruction.

But this time, Mr. Trump, your secretary of state should urge the 60 other donor nations to join the U.S. and demand an end to UNRWA once and for all. It would be a disaster to treat UNRWA as a bulwark of hope the day after the IsraelHamas war is over when it has actually played a key role in keeping alive the dream of a Jew-free Holy Land.
