Israel decimated the group’s leadership last fall and degraded its military capabilities. Can the same strategy work against a far more powerful foe?

The most frightening scenario, considering the strategy Israel has employed in Lebanon, would be a series of attacks targeting lower-level figures, which could escalate to higher-level figures depending on the response or lack thereof, creating an even more frightening scenario than the current one.

The Israeli army says 200 jets struck more than 100 sites across Iran in a large-scale attack. Israel’s military says it launched a wave of strikes on Iran, hitting key nuclear facilities and killing senior Iranian commanders and nuclear scientists in a major attack.

What was the context for these attacks? What kind of damage has been inflicted? How has Iran responded? How has the world responded, and what happens next?

The Lebanese militant group Hezbollah was long considered Iran’s first line of defense in case of a war with Israel.
