Stop with this inane exit strategy BS. There was no exit strategy for the Revolutionary War, the Civil War, WWII, Korea, or Vietnam. The popular backlash to the Vietnam experience is what brought on this whole belief that we need an exit strategy. I am going to put my trust in the first 6,000 years of human history and warfare over the past 30 and your ridiculous assumption that every war strategy needs a detailed exit strategy. You have yet to cite me anywhere in the annals of military history, text, etc. that this "exit strategy" is addressed. In fact, you stated that apparently book learning on the subject is null. Yet, you have no actual experience in combat...
I am going to be obliged to come to the conclusion that you are simply trying rest on your "I was schooled at USMA" laurels. Although, I doubt you were ever given "exit strategy" instruction there either.
