Now Jafari and his supporters are allegedly preparing new potential horrors. Western intelligence agencies have acquired a plan marked “top secret” and code-named “Murky Water.” Together with Ali Fadawi, an admiral in the Pasdaran, Jafari is thought to have proposed a senseless act of sabotage: to intentionally cause an environmental catastrophe in the Strait of Hormuz.

The goal of the plan seems to be that of contaminating the strait so as to temporarily close the important shipping route for international oil tankers, thereby “punishing” the Arab countries that are hostile to Iran and forcing the West to join Iran in a large-scale cleanup operation — one that might require the temporary suspension of sanctions against Tehran.

Western intelligence experts speculate that Jafari’s planned operation is an expression of growing frustration. Contrary to claims made by Iranian Foreign Minister Ali Akbar Salehi in an interview with SPIEGEL last week, the embargo imposed on Tehran is causing far more than “discomfort.” Iran derives more than 50 percent of its government revenue from oil exports, which declined from about 2.4 million barrels a day in July 2011 to about 1 million barrels in July 2012. But Iran has only cut back production by less than a quarter, because of the technical complexity and expense involved in temporarily capping wells.
