The top US military officer, Joint Chiefs of Staff Chairman Gen. Dan Caine, said that American military objectives in Iran will not be achieved overnight and that more US casualties are expected as the air campaign continues. Caine's comments came after several US warplanes were mistakenly shot down by Kuwaiti air defenses, resulting in four American deaths so far. The US-Israeli air strikes against Iran were launched on February 28 and have targeted the Iranian regime's missiles, navy, and other security systems.

Why it matters

The US military operation against Iran represents a major escalation of tensions between the two countries that have been adversaries since 1979. The campaign carries significant risks, including the potential for further US casualties and an expanded regional conflict, as Iran has already retaliated with missile and drone strikes on US allies in the region.

The details

In a news conference, Gen. Caine stated that 'This is not a single overnight operation' and that the military objectives 'will take some time to achieve, and in some cases will be difficult and gritty work.' He acknowledged that the US expects to take additional losses, but said the armed forces are unified 'against a capable and determined adversary.' Department of War Secretary Pete Hegseth also said the operation would not turn into an 'endless war' like the conflicts in Iraq and Afghanistan.

  • The US-Israeli air campaign against Iran was launched on February 28, 2026.
  • On March 2, 2026, Kuwaiti air defenses accidentally shot down three US F-15E fighter planes.
