Despite stunning early successes in Israel’s unprecedented strikes on Iran, a weekend of intensive bombardment and retaliation is raising questions about Israel’s exit strategy – how it can end this conflict with its ambitious goals achieved.

Israel has carried out an extraordinary series of attacks on Iran, aiming at their nuclear facilities and top military officials. The operation is expected to last “weeks, not days,” according to Israeli and US officials.

Iran fired a new wave of missile attacks on Israel early Monday, triggering air raid sirens across the country as emergency services reported at least five killed and dozens more wounded in the fourth day of a conflict between the regional foes that showed no sign of slowing.
