Israel may succeed in taking out Iran’s air defenses, ballistic missiles and much of its nuclear program. But that would still leave hundreds of thousands in the military, the Revolutionary Guard and forces known as the Basij, who played a key role in quashing waves of anti-government protests in recent years.

The Israeli strikes in Iran have killed over 200 people and injured hundreds of others, Iran’s Health Ministry said Sunday. Human rights groups say the numbers are probably much higher. Iranian media reported explosions and heavy air defense fire in the capital of Tehran and explosions in the northwestern city of Tabriz on Tuesday.
