U.S. President Donald Trump has a wide range of military assets in the Middle East and across the globe to bring to bear in a potential fight against Iran as he weighs one of the most momentous foreign policy decisions of his administration.

That arsenal includes powerfully destructive bombs, long-range stealth bombers, an aircraft carrier strike group, Navy destroyers and U.S. troops — offering Trump multiple options if he decides to intervene more directly in support of Israel. Some resources like the B-2 bomber are in the U.S. while other assets are either in the region or on the way.

It’s unclear whether Trump will deepen U.S. involvement beyond helping Israel defend against Iranian air attacks as he has done in recent days. On Tuesday afternoon, the president gathered his national security staff for a White House Situation Room meeting.
