So, on the one hand, the United States was actively assisting Iraq with its intelligence and logistical support -- which included the supply of “numerous items that had both military and civilian applications, including poisonous chemicals and deadly biological viruses” -- and was giving further indirect assistance by reflagging and escorting Kuwaiti tankers which were shipping cargoes whose proceeds were being used to finance the Iraqi war effort. The United States had no logical or legal reason to support Iraq against Iran: Iraq was the aggressor State who had launched an unprovoked invasion of Iranian territory; Iraq was the party who was using chemical weapons and launching missiles against Iranian civilians; and Iraq was the party who took the conflict to the Persian Gulf by attacking both Iranian and neutral shipping. Iran, on the other hand, was the victim; Iran used only conventional weapons in its defence and respected the laws of warfare; and Iran was the party in whose interest it was to keep the Persian Gulf open to shipping.

There's lots more.
