The West has to take seriously what NK says and does.  Its no longer an option to just wait and see how things turn out.  Hasn't history taught us that if you're not willing to pay with some blood now you'll surely pay with added buckets later.  The US has no choice but to go in and clean house with NK, the longer they wait the costlier it will get in lives.  Sad but true.  This is what happens with weak leadership who try to appease madmen.  Appeasement only makes the NK more dangerous.
