I agree with you, D.L. If the West can find the resolve to defend itself, defense of the oil fields will be easy.
The hard part's finding the resolve.
One thing this author does not understand: Liberating the oil in Iraq means a big drop in world oil prices. This means that the Saudis will loose huge sums of money. Which means that they will have to stop funding their worldwide terrorist school system.
That is, an attack on Iraq is an attack on Saudi Arabia. That's why the Saudi's are apoplectic about this.
The big problem is that lower oil prices also hurt the Russians, big time. That is why Russia opposes the war. How the Russia card plays out is the most important, but little watched, issue on the table today.
