The quote from JFK is good and all, but I don't see that sentiment reflected in our Constitution, nor do I see it reflected in the reality of the times in which we live. What I DO see in our Constitution (which IMO should be the determining factor in whether we attack another country) is this:
Our Constitution states that we seek to secure the blessing of liberty for ourselves and our posterity. It says nothing about requiring us to do it for the whole world. As a human being I care that people are being killed and repressed all over the world. But as a realist and as a person who would likely be called upon to implement a policy of intervention, I'm not eager to see us get involved overseas. Unless, again, it's in our national interests. If intervening somewhere gets us something that we really need, like natural resources, strategic positioning, maintaining the balance of power, etc., then I'm all for it. Otherwise, I'm quite happy to let people sort things out on their own. So if going into Syria gains us something that is markedly greater than its potential costs, then I would happily go along with it. But I have yet to see the "what's in it for us" angle that would gain my support for the endeavor.
We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.
