As you hint at in your editorial “MAGA’s Misguided Isolationists” (June 20), the ferocity of Israel’s counteroffensive has left its critics dazed and confused. A week or so ago, they officiously reminded everyone that the U.S. intelligence estimate about Iraq was mistaken. The implication? Only a fool would trust any warnings about Iran that emanated from the bowels of the Deep State. Many of these critics still deny that Iran attempted to murder Donald Trump last year. Yet as the president deliberated about striking Iran’s nuclear facilities, they declared their trust in the American intelligence community and its assessment that Iran wasn’t working toward a bomb.

What accounts for their Damascene conversion? Little about the intelligence community has changed in recent days, other than CIA director John Ratcliffe’s discounting that assessment and stating that Israel had stopped Iran’s bomb program at the “one-yard line.” The isolationists’ ideology evidently requires facts to rearrange themselves.

Polls reveal that actual “MAGA Republicans” and Trump voters overwhelmingly supported the Jewish state’s air campaign and the American strikes. They seem to place as much faith in Israel’s intel as the president does.

Erasing Iran’s nuclear program is important, and Mr. Trump needs the best information available. He won’t get it from the shrieks from the fever swamps.
