Because of the Carter Administration’s mess up in Iran and the turmoil created there Iraq thought it would be a good time to attack and take over Iran’s southern oil fields. This was in the early 80’s. Iran counter-attacked with such overwhelming force, the Iran army’s “human wave” that there was a real threat that Iran would defeat and conquer Iraq and be in control of vast middle eastern oil. This could not be allowed to happen so the Reagan Administration armed and supported Iraq enough so the two nations would fight to a stalemate. BRILLIANT!
The reason the Reagan Administration found it necessary to arm and support Iraq was because of Carter’s mishandling of Iran and America’s ally the Shah.
I know the history and the USA did not arm Iraq with WMDs. Ever!
