Blockade of Strait of Hormuz and Major Naval Sieges in Modern History
The Strait of Hormuz, a global energy artery, is effectively blocked after the U.S. and Iran imposed tit-for-tat bans. It is one of the most notable modern naval blockades, alongside historic sieges from Gaza to Biafra. The tactic of naval blockade, which cuts off an enemy's supplies without ground invasion, has a long and often devastating history.
