I know you were on the phone very early this morning with one senator, an ally of the president.

What's the buzz on Capitol Hill?

How are these attacks going over with Democrats and Republicans?

And kind of to the point we were discussing before the break, how much willingness is there in Washington for the U.S.

to get into a sustained military operation here?

Jared, how does that compare to the reaction to all this from the Gulf states?

There's already really been quite a long list of countries who've been pulled into this.

I want to return to Iran.

Jared, earlier you had sort of mentioned the role that the U.S.

envisions for protesters that are sort of picking up and delivering the fatal blow of this operation, which would be a change in Iran's leadership.

Let's hear a clip of President Trump on that point.

Have we seen people hitting the streets in Iran, Jared?

And what should we be watching for there in the days, weeks to come?

And Alex, crucially, there hasn't been a leadership vacuum yet.

I mean, there may have been attacks trying to target members of the Iranian leadership, but from what we've been able to determine, no one's been killed.

There isn't any openings to be filled.

Jared, how realistic is all of this?

I see Iran's foreign minister has now come out and called the prospect of regime change mission impossible.

I've been speaking to Wall Street Journal Middle East correspondent Jared Malson in Istanbul and national security reporter Alex Ward in Washington.

Jared, Alex, thank you both so much.
