Israel and Iran both have little incentive to stop and no obvious route to outright victory. Much depends on President Trump.

Israel's military spokesman said that the country’s air force has destroyed 120, or about one-third, of Iran’s surface-to-surface missile launchers since the beginning of its confrontation with Iran.

Hundreds of civilians, mostly in Iran, have been killed by dueling airstrikes despite international pleas for de-escalation.

Israel identified and struck missile launchers in Iran overnight, the Israel Defense Forces said Sunday morning. "Over the past hour, the IAF completed an additional series of strikes on storage and missile launch infrastructure sties in western Iran," the IDF said in an update on the Telegram messaging app at about 8 a.m. in Israel.
