Greed. The US as a history of supporting dictators as long as American corporations can operate in there country and exploit there population.The US is also the worlds largest arms dealer.It does not matter where there is conflict in the world,the US is making money supplying weapons.A lot of the cases both sides.Afghanistan is a great example.Since Americans are being killed by weapons supplied by the US from the Russian invasion.Why did the Russians invade? To get rid of the terrorists.The US as always supported terrorists that attack there enemy.Saddam was a real friend to the US when he was at war with Iran,but as soon as the war was over he was no longer a friend .
