Israel's air force achieved a "remarkable feat," said William Freer, a research fellow for national security at the U.K.-based Council on Geostrategy.

As Iran fires masses of ballistic missiles, Israel’s vaunted air defenses are being tested like never before. Iran launched around 200 such missiles at Israel on Friday night — in retaliation for a wave of Israeli strikes that day — and 70 or so on Saturday evening, according to the Israel Defense Forces. More came on Sunday and Monday.
