The question of whether the U.S. will intervene to support Israel or attack Iran has heightened tension in the global financial markets. A key indicator of military action will be the deployment of B2 bombers, which are capable of delivering the GBU-57 Massive Ordnance Penetrator designed to destroy Iran's underground nuclear facilities.

The U.S. military action not only affects Middle Eastern geopolitics but also has direct implications for the Taiwan Strait situation, international markets, and U.S. domestic politics. According to The New York Times, the U.S. has repeatedly simulated attacks on Iranian nuclear facilities over the past 16 years, second only to simulations related to potential Chinese aggression against Taiwan. Not assisting Israel could send a wrong signal to China, suggesting the U.S. would not intervene militarily.

Trump 2.0 has escalated American isolationism, affecting market confidence in dollar assets. Supporting Israel to eliminate the Iranian nuclear threat could demonstrate a commitment to allies and potentially relieve some market pressure to sell, thus rebuilding confidence.

Trump supporters are divided on whether to intervene in Iran. Anti-war factions argue that Trump pledged to stay out of wars not involving the U.S., while more hawkish voices within the Republican Party advocate that active intervention is necessary to swiftly mitigate the Iranian nuclear threat and end conflicts in the Middle East.
