How Trump Decided to Strike Iran

Standing at the lectern in the White House briefing room on Thursday afternoon, Karoline Leavitt, the White House press secretary, read a message she said came “directly from the president.”

Because of the “substantial chance of negotiations” with Iran that could bring the United States back from the brink of jumping into the war in the Middle East, President Trump’s statement said, he would make a decision about whether or not to strike Iran “within the next two weeks.”

Mr. Trump had been under pressure from the noninterventionist wing of his party to stay out of the conflict, and was having lunch that day with one of the most outspoken opponents of a bombing campaign, Stephen K. Bannon, fueling speculation that he might hold off.

It was almost entirely a deception. Mr. Trump had all but made up his mind to bomb Iran’s nuclear facilities, and the military preparations were well underway for the complex attack. Less than 30 hours after Ms. Leavitt relayed his statement, he would give the order for an assault that put the United States in the middle of the latest conflict to break out in one of the world’s most volatile regions.
