Recall that the US and our allied sold Iraq conventional weapons, duel use technology, and precursor material to make chemical weapons that were used on Iranians as well as Iraqi Kurds. The Halabja massacre remains the largest chemical weapons attack directed against a civilian population in human history. Also don't forget Raygun's deal that sold Iran Missiles in the Iran/Contra scandal. We've been poking that hornets nest since the Theocrats took over. The expectation was that they would come back to the US fold to purchase spare parts for their US military hardware. But Vietnam had a supply of US weapons that they were more than willing to sell to the New Iranian regime.
