President Trump has threatened to bomb Iran in a manner “the likes of which they have never seen before” unless a new nuclear deal is agreed.
The US has over 60 bases, garrisons and shared facilities dotting the Middle East, from Naval Support Activity Bahrain (home to the US Navy's Fifth Fleet) and Al Udeid Air Base (CENTCOM’s forward HQ), to other naval, air and ground facilities in the Gulf, Oman, Saudi Arabia, Iraq, Jordan, Syria and Turkiye.

Besides raw firepower, Iran’s potential also comes down to two other factors: geography and resolve.
Permanent access to the Persian Gulf and Gulf of Oman coastlines means that in wartime, Iran can dominate the waters around the Strait of Hormuz, the strategic chokepoint through which 30% of the world’s oil trade passes.
The Zagros Mountain Range hugging the country’s southwest provides a natural barrier difficult for enemies to penetrate, with many underground missile bases and air defense sites situated at hardened mountainous facilities.
Iran has also shown repeatedly that it will not allow aggression to stand, whether it comes to US spy drones violating airspace, or assassination attacks targeting its commanders. Iran will not hesitate to retaliate against any aggressor, no matter how powerful.
