An Iranian strike on an American military base in Saudi Arabia, injuring two dozen troops. Two drones targeting a port in Oman, and a strike on the Kuwait International Airport. Workers at an aluminum facility in Abu Dhabi wounded by a missile and drone attack.

President Trump has said that the United States has all but obliterated Iranian military abilities, portraying Iran as a defanged adversary. The U.S. military says that the number of attacks Iran has launched has declined by roughly 90 percent from the opening days of the war, and the Israeli military says it has rendered roughly 70 percent of Iran’s hundreds of missile launchers inoperable.

But a series of attacks against Israel and Gulf countries in the past several days is only the latest evidence that Iran retains enough missiles and drones to destabilize the region and inflict a punishing cost on its foes, while signaling that, contrary to Mr. Trump’s declarations, it is still very much in the fight.

Millions of Israelis are still rushing into bomb shelters day and night to take cover from Iranian missile fire. The daily routine of sirens and booms sows fear and paralysis. Seven people were injured in central Israel on Thursday after missile barrages, according to the country’s emergency service. Surveillance video captured footage of two people rushing out of harm’s way before a silver car they were standing near exploded then pinwheeled through the air. On Friday, a Tel Aviv man was killed by a bomblet from a missile with a cluster-munition warhead.

Even when Iranian weapons are intercepted, they can still inflict damage. Two people were killed in Abu Dhabi on Thursday when they were struck by shrapnel falling from an intercepted missile.
