What are US troops doing in the Middle East and where are they?

The United States and Iran are scheduled for talks in Oman amid President Trump’s threats of military action if Iran does not limit its nuclear program, which Iran denies pursuing. The U.S. military maintains around 30,000 troops in the Middle East, with a significant presence in Iraq and Syria, and has recently increased military assets, including aircraft and carriers, as tensions rise. U.S. bases in the region are generally secure, although personnel in Iraq and Syria face frequent attacks from Iran-backed forces amid ongoing conflicts.
