The posts on this thread make one mistake. It matters not whether we buy from Saudi Arabia or if the French replace us. It is a world wide market. Oil is a commodity. The issue is the overall world supply and demand, which sets the world wide price. The more supply, the lower the price and vice versa.
So if we can double the amount of oil pumped by the Iraquis or by the Russians, we put the Saudis into a terrible bind. Either they accept the lower price caused by the increased supply or they cut their production. Either way, they make less money. Either way, there is less money funnelled to terrorists and terrorist schools all over the world.
And, what's nice about it is that it doesn't matter if the French start buying Saudi oil. It doesn't matter because the price has fallen.
This is why the saudis and the russians are so opposed to our invading iraq. Neither want more iraqi oil on the market.
Liberate Iraq!
