A top U.S. general reportedly warned his superiors this week that Washington lacks sufficient military power to protect the United States’ allies in the Middle East.

The U.S. has positioned naval destroyers in the eastern Mediterranean Sea to stabilize the Middle East and bolster Israel’s security for years, with the destroyers rising to particular use in recent months, as Iran has carried out attacks on Israel and 14 other countries in the region. However, Gen. Alexus Grynkewich, the head of U.S. European Command, told the Pentagon that he lacks sufficient naval forces to continue protecting Israel from incoming ballistic missiles from Iran and its terrorist proxies in the region, according to a Washington Post report published Friday.
