If Israel does attack Iran's nuclear facilities, it will undoubtedly result in a regional war after Iran and Syria signed a mutual defense agreement on Sunday.

Kuwaiti media reported that the agreement was signed at the weekend while Iranian Defense Minister Ahmad Vahidi was visiting Damascus.

Speaking to Syrian media, Vahidi said the agreement was a strong deterrent to an Israeli strike on his country's nuclear facilities. Vahidi said that in addition to a Syrian response, Iran would retaliate for any strike on its nuclear facilities by firing ballistic missiles at Israel's nuclear facilities.
