The Strait of Hormuz is a very narrow strip of water that links the Persian Gulf to the Oman and Arabian Seas.
For Iraq, Iran, Saudi Arabia, United Arab Emirates and Qatar, this strait must be navigated in order for their ships to supply 40% of the earth’s oil exports to world markets. This is over 20 million barrels a day!
Iran is saying that if Israel and/or the United States attacks her, she will close the strait. And she could as Iran borders the strait on three sides.
An Iranian blockade, of course, would be shooting herself in the foot regarding her oil revenue but she would cause instant global economic chaos.
