You dont need to sign up, just get on a plane fly over there and join or start an army of your own....Your call.
While I think it's tragic that you've buried war dead in your family and I offer my sincere condolences, I would ask, though I can anticipate your answer, was it worth it? I mean, unless we are talking about WWII or perhaps the Cold War, I can't think of a single war after WWII that was worth it's cost in American lives.
We're getting less oil from the ME? That is your response? So what?
oil demand has continued to rise and when you add in the fact that it was ~$1.50 up to ~2005 and after it's averaged over ~$2.50, I'd say there is more money than ever flowing from the US to the ME. Add to that, the fact that we consume more than 3 times the next highest consumer (China) I'd say we're largely responsible for the wealth that flows into the hands of the people that "want us dead". We are funding the capability to make war against us.
"National Revenge"? That is about the dumbest thing I've ever heard of. Revenge is emotional response. There is nothing rational about that word. Nothing you've said is rational, it's all emotional despite accusing me of the same, though you didn't give an example.
How does "National Revenge" accomplish anything rational? Try to think more than 1 layer deep. If you eliminate today's threats, what about the next generation of children that grow up hating so much they are willing to strap bombs to themselves just to kill innocents? Your "revenge" doesn't deal with that problem, it only makes it worse, that is, unless you are prepared to commit genocide in order to accomplish your goals?
