The US will send an advanced air defense system — Terminal High Altitude Area Defense (THAAD) — and troops to Israel even after Iran warned Washington to keep its forces out of Israel, the Pentagon said. 

Defense Secretary Lloyd Austin authorized the deployment of the THAAD on Sunday, at the direction of President Joe Biden, said Pentagon spokesman Maj. Gen. Pat Ryder. 

The system — which is designed to shoot down ballistic missiles like the ones the Iran fired into Israel on Oct. 1 — is set to protect Israel following Iran’s massive barrages on the Jewish State. 

Israel has vowed to retaliate against the Islamic Republic — further spiking already sky-high tensions in the region.

“This action underscores the United States’ ironclad commitment to the defense of Israel, and to defend Americans in Israel, from any further ballistic missile attacks by Iran,” Ryder said.

The Pentagon’s announcement came just hours after Iranian Foreign Minister Abbas Araghchi warned the US not to deploy any soldiers to Israel. 

“The US has been delivering record amount of arms to Israel,” Araghchi wrote on X. 

“It is now also putting lives of its troops at risk by deploying them to operate US missile systems in Israel,” he added.  

It remains unclear when and where the THADD battery and the troops will be active in Israel. 

The THADD system generally consists of six, truck-mounted launchers, 49 interceptors and radio and radar equipment, with 95 soldiers needed to operate. 

The US Army has seven THAAD batteries, according to an April report by the Congressional Research Service. 

One was previously deployed to the Middle East to bolster protection for US troops stationed in the region following Hamas’ Oct. 7 terrorist attack. 

Iran has said it will retailiate in turn for any attack on its soil.

“While we have made tremendous efforts in recent days to contain an all-out war in our region, I say it clearly that we have no red lines in defending our people and interests,” Araghchi warned.
