And speaking last night, President Trump pledged to push on, saying the U.S.

would avenge the death of three American troops killed over the weekend.

Meanwhile, the U.S.

is far from alone in coming under fire, as Israel, a number of Gulf states, and even the Mediterranean island of Cyprus, home to a British military base, find themselves on the receiving end of Iranian counterattacks.

Here to make sense of what's going on is Wall Street Journal Middle East editor Andrew Dowell.

Drew, 2,000 targets struck within Iran.

Do we know what those are?

Can we start to sort through what has actually been achieved here?

How are we measuring progress in this campaign?

Drew, we should probably add that in addition to those targets, the Associated Press is reporting that according to the Iranian Red Crescent Society, these attacks from the U.S.

and Israel so far have killed 555 people in Iran.

We don't know how many of those are members of the military versus civilians, but that's a factor here as well.

Let's talk about how Iran is fighting back.

We have seen attacks

using drones and missiles against military bases, but also civilian facilities, hotels, airports, and these attacks occurring in places like Dubai and Abu Dhabi and now affecting hundreds of thousands of civilians who are all getting caught up in this.

You indicated earlier the intention here, bringing the fight to these countries, maybe an effort on Iran's part to draw this to a close.

But at least our chief foreign correspondent, Yaroslav Trofimov, reporting sort of overnight, perhaps it could have the opposite effect, kind of deepening the resolve of these countries to fight back against Iran, maybe put this nuisance to bed once and for all.

Is that possible?

A lot to watch.

And that's not all of it, because we finally have to mention there is now a battle rapidly escalating between Iran's proxy in Lebanon, Hezbollah, and Israel.
