History

Historical Context

In 1988, during the Iran-Iraq War, the U.S. Navy launched Operation Praying Mantis, targeting Iranian naval assets in retaliation for attacks on U.S. vessels. This operation resulted in the destruction of multiple Iranian ships and platforms, escalating U.S.-Iran tensions. The recent sinking of the IRIS Dena echoes this historical conflict, highlighting ongoing maritime disputes and the potential for further military confrontations in the region.
