I cannot argue with the points you have made. Indeed, I feel that your post supports a point that you did not make explicit. Such risk-averse behavior seems to me to be explainable by the fact that the war in Iraq was a war of choice, which is a euphemism for something else. Civilians "tire" of all wars. But when a war cannot be explained on the basis of strategic necessity, much less on the basis of immediate national survival, then it is not surprising that the pervasive vibe in-theater is not very satisfying for warriors. Here's hoping the next war will fulfill your expectations!
It is easy for me to misunderstand what you could mean by, "Here's hoping the next war will fulfill your expectations!" I've met a lot of people who would say something like that with hate in their heart. But I've been promoted by people who would say something like that in earnest. Perhaps you'd like to be more explicit? I would also be interested in your perspective on strategic necessity as it relates to both global and domestic concerns.
