The Israeli and U.S. Air Forces this week conducted a significant joint military exercise over the Mediterranean Sea, their first collaboration of this scale in two years.

Dozens of fighter jets, strategic B-52 bombers and refueling aircraft participated, simulating coordinated strikes on shared targets, Israel’s Kan News public broadcaster reported on Tuesday.

The drill comes as foreign reports suggest Israel is urging the United States to take joint action against Iran’s nuclear program. Israeli Defense Minister Israel Katz emphasized collaboration with Washington to prevent Tehran from obtaining nuclear weapons. Meanwhile, Foreign Minister Gideon Sa’ar warned that diplomatic efforts are faltering, leaving military action as a possibility.
