The United States is deploying one of its most advanced missile defense systems, along with approximately 100 U.S. troops, to Israel, marking an escalation of U.S. involvement in the growing conflict in the Middle East.
This move comes amid expectations of a significant Israeli assault on Iran. The deployment, which includes the Terminal High Altitude Area Defense (THAAD) missile system, represents the first major U.S. troop presence in Israel since the Gaza war began. The timing is critical, coming just weeks before the U.S. presidential election, where the U.S. role in the conflict has become a contentious issue. U.S. officials have been pressing Israel to refrain from targeting Iran’s nuclear and energy infrastructure to avoid a larger escalation that could impact the global economy.
The U.S. has already provided over 50,000 tons of military equipment to Israel since the conflict’s escalation last October, as reported by Israel’s Defense Ministry. Israel’s Defense Minister Yoav Gallant has promised a powerful response to Iran following a ballistic missile barrage launched by Tehran on October 1. The Iranian assault, which followed Israel’s assassination of top Iranian, Hamas, and Hezbollah officials, caused minimal damage due to successful U.S. and Israeli missile defense efforts. However, a Hezbollah drone strike in northern Israel over the weekend showed vulnerabilities in Israel’s defense, killing four Israeli soldiers.
“The THAAD battery will enhance Israel’s integrated air defense system,” said Pentagon spokesman Pat Ryder, emphasizing the U.S. commitment to protecting both Israel and Americans in the region from further Iranian missile strikes.
The conflict has also exposed deep divisions within U.S. politics. While Kamala Harris and President Trump have voiced strong support for Israel, Democrats remain divided, with some criticizing the administration for its support of Israeli military actions. Meanwhile, Republicans have attacked the Biden administration for its handling of the crisis, particularly in the wake of Hamas’s deadly attack in 2023.
Despite some disagreements between Biden and Israeli Prime Minister Benjamin Netanyahu, Biden’s decision to send the THAAD system signals his continued trust in Netanyahu’s leadership. However, some experts, like former U.S. Army officer Harrison Mann, question whether Netanyahu will stick to his promises to avoid targeting sensitive sites once U.S. defense systems are in place.
The THAAD system, which is designed to intercept ballistic missiles, is purely defensive and does not have any offensive capabilities. The shipment of this system, expected to arrive at an unspecified date, is seen as part of Biden’s strategy to use diplomatic “carrots” to influence Israel’s military decisions.
At the same time, the Biden administration imposed new economic sanctions on Iran, targeting its petroleum industry in hopes of dissuading Israel from striking Iran’s energy assets. Still, experts warn that the increased U.S. troop presence in Israel raises the risk of American casualties, potentially dragging the U.S. further into the conflict. If Iranian forces or their allies in Iraq or Syria harm U.S. personnel, the likelihood of a direct U.S. military response increases, according to Miller.
The U.S. previously deployed the THAAD system to the Middle East after the October 2023 attack on Israel and during a 2019 training exercise. Israel’s existing missile defense systems, such as Iron Dome, Arrow, and David’s Sling, will be bolstered by the addition of the THAAD system, Pentagon officials said.
