We should be more concerned about China and their growing power. There are far more people in China, with the ever increasing need for resources. Our attentions are focused accross the wrong pond. To hell with the Middle East (ahhh hell we can't do that because of our ties with Israel, and our precious oil that we choose to be dependent on through foreign suppliers). If we ever had to fight China there would almost certainly be bigger consequences as far as weapon useage.
