Hi Lee, thanks for the great explanation of why the U.S. empire wants war with Iran.
The U.S. propped up the dictatorship of the Iranian monarch, the Shah, before the revolution of 1979 overthrew his murderous regime . It is clear the U.S. wants to restore a similar puppet regime to power in Iran.

We should not forget that Iran is a focal point of Shia resistance to the genocidal Wahabis in Saudi Arabia who are funding the head chopping jihadis in Syria.
Plus, Iran has the fourth largest oil reserves in the world. This oil is of a much higher quality and far cheaper to produce than American fracking oil.
