And what exactly does that have to do with it?
The Gulf War was about oil. What was our backing of Afghanistan about?
Very simplistic, in fact childish view. It was not the oil, but the power that oil brings with it. If it were only about oil, we would have done nothing to stop Sadam from taking over the entire Persian Gulf and having all the oil. We get less than 20% of our oil from that region. We could easily have been like Switzerland and found a way to make business deals with him. We could have bought it from him just like we buy it from others. He likes money too.
The problem we had was the prospect of a tyrant like Sadam controlling both world oil prices and having a nearly unlimited source of cash to finance his military plans. Keep in mind, he is the guy who dumped chemical weapons on his own people. He would have done the same to anyone in the region that resisted him.
Do you really think it would have been a good idea to sit back and allow him to do what he wanted in the Mid East? Was Munich a good idea in 1938?
Supporting the Afghans in the 80s was about coming to the aid of a country invaded by the Soviet Union. Afghanistan had been a friend and ally of the US throughout the cold war and supporting them in a war with the Soviet Union is what we should have done.
