Kharg Island is about 400 miles from the Strait of Hormuz and sits just 15 miles off the Iranian coast. If the U.S. were to take the island, any soldiers there could be subject to an onslaught of Iranian drones and missiles. Moreover, it is unclear if the seizure of the island would generate enough pressure on the Iranian government to reopen the strait.
What is left? Rowboats? Canoes? Any surface craft can be destroyed long before it reaches the Island.
I heard they have speedboats lol
