Worse, sageantoine, if "war is the only solution" then the U.S. is in REAL trouble.  

How'd it do, in the end, in Viet Nam?  Iraq? Conquers the place and then fumbles, bumbles and allows ISIS to take root there.  Afghanistan? 16 years and three Presidents later, 8,000 troops still in the place. Thousands more in Iraq;  U.S. and other coalition forces bogged down--it takes over 6 months to take a medium sized city inside Iraq's own border from a rag-tag force less than a third the size of the "liberators."  Don't believe it's done yet. 

As you say, "very well thought out."  

Just suppose that, the U.S. manages to flatten North Korea before they can launch "the big ones."  What then?  Iraq all over again?
