I don't need to show you proof, you readily admit the German government has allowed the sale and shipment of chemical warfare materials to Saddam Hussein.
The United States has never allowed this.
The UK and USA sold very little to Saddam, most of it was in the form of transport vehicles and helicopters. The United States did not arm Saddam, the French, Russians and Chinese provided Saddam Hussein with the vast majority of military hardware...
Nor did the United States put Saddam in power, the Soviets did...
Excuse me, but: are you dumb? Where did I post that? "Allowing" requires an act of will, while "not knowing" certainly implies no will at all.
Therefore, prove your claims or STFU!
