The dependence is 100% mutual and both sides know it, so it's a win-win partnership that has survived these past 80 years. I don't find any down side to that. We are, after all, co-dependent with many countries. As least the Saudis have proved themselves through thick and thin these past 80 years.
Our military is there, in large numbers, an UNHEARD OF thing in ANY other Arab and/or Muslim country. They trust us because we have proven our trust to them as well.
You have a very valid point. Thanks,
