History

Historical Context

The 1988 downing of Iran Air Flight 655 by the USS Vincennes, which killed 290 civilians, intensified U.S.-Iran tensions following the U.S. Navy's Operation Praying Mantis. This operation targeted Iranian naval assets in retaliation for attacks on U.S. vessels during the Iran-Iraq War. The recent sinking of the IRIS Dena in 2026 echoes this fraught history, underscoring ongoing military and diplomatic challenges in the region.
