U.S. intelligence shows that Iran has been preparing for the possibility of attacking American bases.

On June 18, according to the New York Times, U.S. officials familiar with the matter said that Iran has prepared missiles and other military equipment, and once the United States joins Israel's war against Iran, Iran will launch attacks on U.S. bases in the Middle East. The U.S. has sent about 36 tankers to Europe that could be used to help protect fighter jets at U.S. bases or to extend the range of bombers that could launch attacks on Iran's nuclear facilities, the report said. As Israel presses the White House to intervene in the conflict with Iran, U.S. officials are increasingly worried about a wider war. If the United States joins Israel in launching an attack on Fordow, Iran's vital nuclear facility, the Iranian-backed Houthis will almost certainly resume attacks on ships in the Red Sea, officials said. They added that pro-Iranian militias in Iraq and Syria may try to attack US bases there. In the event of an attack, Iran could begin laying mines in the Strait of Hormuz, a tactic designed to trap American warships in the Persian Gulf, other officials said.
