If you are going to pull the ally card into it then remember one thing! The U.S. has more allies than N.K. would ever get. On top of it many of our already have very well strategically placed war machines that are VERY well trained!

Your argument is valid save for fact towards the end you use a select group of people to pick on. The fact is the evil nature of many in America is a problem period! Excessive drug use, alcoholism, sexual abuse and sexual misconduct, sue happy people and general self glutens in most any area that our freedoms allow us to feed is the issue. I still think it to be the best Country in the World. However our arrogance is what is killing us. It was the same with the Romans. There arrogance, over burden use of power and public misconduct took them down! I guess we learned nothing!

People keep talking about how Iraq and Afgan. etc. were never won. We DID NOT and ARE NOT trying to defeat those countries! We were only trying to oust specific groups within those countries PERIOD. Trying to methodically remove a group or groups is a TON harder than defeating the entire country as a whole. So your logic is mistaken. If we truly wanted to just defeat a country we could use some very definite tactics to wipeout just about any communist country on the map and most others in a TRUE all out war. Though the stupidity of such a war would cost humanity tons!
