The possibility of Iran attempting to close the Strait of Hormuz to tanker traffic has increased significantly in recent weeks, as has the possibility of a Persian Gulf War, especially with the Islamic Republics’ intentional destruction of a U.S. surveillance drone on June 20.
This act provides weight to Tehran’s threat that it will inflict a heavy toll on U.S. allies in the region if attacked by American forces and will not allow these same countries to export their oil if it can’t export its own.
The memory remains remarkably fresh in Iran of the 1951-53 oil embargo that toppled the democratically-elected government of Prime Minister Mohammed Mossadegh – and the CIA installing the despot Mohammad Reza Pahlavi, the so-called Shah of Iran, in his place.
The impact on oil markets of an Iranian closure of the Strait of Hormuz would be enormous.
Strait of Hormuz Closure
The leadership of the Iranian Navy and the Revolutionary Guard Navy, knowing they could never challenge the U.S. in a conventional naval contest, have been accumulating considerable asymmetric and other capabilities to enable the Islamic Republic to close the Strait of Hormuz since the “tanker war” in the Persian Gulf during the 1980-88 Iran-Iraq War.
These capabilities include thousands of sea mines, torpedoes, advanced cruise missiles, regular-sized and mini-submarines, and a flotilla of small fast-attack boats, most of which are concentrated in the strait region.
