The theory that I essentially take from your (and others) analysis is that your opinion on what to do is right and moral and anything else is not. I would instead state that there is no definitive right decision, just choices that have to be made. There are countless factors going into all these decisions from humanitarian concerns to maintaining international relations to trade concerns to jobs, etc...

Obama put it well on the wtf podcast...the federal government is an aircraft carrier... you can't move it on a dime, you can make nudges and over time the policies change.
