Saudi Arabia stood by while Israel suffered blows from Iranian missile strikes, and some observers say it might have preferred it that way

Iran's missile campaign against Israel and U.S. bases cost Tehran up to $6.6 billion while depleting half its arsenal. Experts call for investment in cheaper interception technologies.

Roughly 25% of all U.S. THAAD interceptors funded to date were reportedly launched in June, and SM-3s were also expended at a worrisome rate.

About 14 percent missile stocks of US' THAAD air defense system were exhausted in shooting down Iranian missiles fired towards Israel during the Israel-Iran war.

Israel and Iran have been enemies for decades — but this is their most sustained direct fighting ever. Here’s how a shadow war erupted into an overt conflict.

Experts say Iran has fired about 700 of its medium-range ballistic missiles, leaving it with anything between 300 to 1,300 left in its stockpile.

"That would be very, very dangerous for everybody," Iran’s Foreign Minister said of a potential U.S. involvement.

Israel's war with Iran in June revealed just how thinly stretched the United States' missile defense systems are globally. America currently has seven Terminal High Altitude Area Defense systems -- known as THAAD -- and two of those were reportedly in Israel during 12 days of fighting with Iran,
