Pentagon General Warns He Lacks Forces to Defend Israel Amid Iran Conflict

Gen. Alexus Grynkewich, head of U.S. European Command, warned the Pentagon this week that he lacks enough military resources to continue defending Israel from incoming Iranian ballistic missiles. Without an additional Navy destroyer, Grynkewich said he would be forced to choose between protecting Israel or the U.S. homeland. The warning underscores the strain five months of conflict with Iran has placed on American naval assets.

What the general told the Pentagon

Grynkewich wrote to senior Pentagon officials that the U.S. currently deploys five destroyers from a port in Spain to the eastern Mediterranean to defend Israel. As of Friday, July 31, only two destroyers—USS Paul Ignatius and USS Roosevelt—were operating in the Mediterranean, while three others were in port at Rota, Spain. A sixth destroyer was expected to be added later this year, but Grynkewich said that plan is insufficient given current operational demands.

Why military resources are stretched thin

The five-month conflict with Iran has strained Navy assets through near-daily operations and increased maintenance needs. Since a U.S.-Iran ceasefire collapsed in early July, the Trump administration reinstated a naval blockade on Iranian ports. The U.S. Navy has also deployed several aircraft carriers and at least 11 destroyers closer to Iran to enforce the blockade and ensure safe passage through the Strait of Hormuz, further reducing available forces for Mediterranean operations.

The competing demands on U.S. forces

Grynkewich must balance Israel’s defense against ballistic and drone threats from Iran and Iranian-backed Houthis in Yemen with NATO’s integrated air defense plans to counter Russian threats in Europe. The Pentagon’s primary mission for European Command is deterring Russian military expansion. Grynkewich’s warning reflects the military’s standard process of informing senior leaders when operational risks exceed available resources, according to Pentagon officials.

Broader military readiness concerns

The strain on naval forces mirrors wider concerns about U.S. military stockpiles. Congress approved $838.7 billion in FY 2026 defense funding, including investments in shipbuilding and munitions production. However, previous assessments found the U.S. depleted advanced missile stocks during months of sustained operations. The destroyers in the Mediterranean carry missiles and radar systems to track and intercept threats, but maintenance and active use have taxed their readiness.

Final Thoughts

Grynkewich’s warning exposes a hard trade-off: the Pentagon cannot simultaneously defend Israel, enforce the Iran blockade, and maintain full NATO readiness without additional naval resources. Congress has funded more shipbuilding, but those vessels take years to deploy.
