Ok, show me the proof! You raised a claim, I want you to prove it. You cannot. The "German government" never sold chemicals to anybody. If ever, it was German companies - before 1991 with the approval of the government (just like lots of American companies - may I remind you of the handshake Hussein/Rumsfeld?), and after it, illegally without the knowledge of the government. Claiming otherwise requires you to provide evidence.
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...
If there is a crime it is called complicity. (Beihilfe)
Of course there is no country that doesn't have clean hands when it comes to international intelligence.
