President Biden was getting ready to leave the White House for an audacious flight to Israel to demonstrate solidarity after the Oct. 7 terrorist attack when suddenly the trip seemed to be falling apart before it even began.

An explosion at a Gaza hospital had reportedly killed or wounded hundreds, the Palestinians were blaming Israel, and Arab leaders were refusing to meet with Mr. Biden when he arrived in the region. The president summoned advisers to the Treaty Room on the second floor of the White House family quarters to answer the question: Should he still go?

A robust debate broke out between his national security and political advisers. Some in the room urged Mr. Biden to scrap the trip. It was not clear what could be accomplished. It might not even be safe. What if Hamas launched rockets at Ben-Gurion International Airport when Air Force One approached? Where would the president land then?

Others argued that he needed to go anyway. He had already announced the visit. They should not lurch from one decision to another. And preliminary U.S. intelligence indicated that Israel was not responsible for the hospital explosion.

Finally, Mr. Biden weighed in. “I’ve got to go,” he said. “I’ve got to see these guys face to face.”
