I don't want to touch the "chickenhawk" argument, but what I do think is this, there is a troubling predilection for military intervention/solutions in this country that is in some ways indifferent to the military itself.
The burden of proposed military solutions and international interventions are carried by a minority in this society - soldiers, their families, veterans, etc. that volunteer. When policy decisions are made by those that no longer have serious risk then the inventions get easier.....and Kuwait, Somalia, Kosovo, Iraq start to come in succession. It is in some ways like having a credit card with someone else's name on it. When you use it the first time maybe you have weighed the option of using it very thoughtfully, after all, it doesn't have your name on it, what am I doing here? But once you realize the bill doesn't come to you, it gets easier to use the second time, and still easier the next.
Sure you rationalize, it is for moral reasons, it is for the good of others, it is the right thing to do because this is an exceptional circumstance I'm using this card, but in the end, that credit card still doesn't have your name on it. It has the name of some marine, some soldier, some airman, some sailor, somebody else.
Who doesn't love the person that pays for everything?
