Meanwhile, the White House has said it will not detail private diplomatic conversations when Reuters asked about Iran’s new proposal to the United States that was submitted to Pakistani mediators.

I do have the impression from some of the briefings that I have received, as well as other sources, that an imminent military strike is very much on the table.

There really is no coherent strategy, which came across very vividly and graphically in the hearing today with Secretary Hegseth.
