As tensions with Washington escalate, Iran threatened retaliatory strikes on U.S. military bases across the Middle East, fueling fears of a wider conflict. Analysts say one base remains a clear red line: Incirlik Air Base in NATO-member Turkey. The facility hosts U.S. and NATO aircraft and is believed to store American B61 nuclear bombs under NATO’s nuclear-sharing program, making any attack highly escalatory. Experts warn a strike on Turkish soil could trigger NATO’s Article 5 and isolate Iran further. The standoff unfolds amid unrest in Iran, shifting U.S. troop deployments, and mounting regional uncertainty.
