North Korea could send a missile to one of our allies in either Japan or South Korea.  
But I suppose folks like you think "I'm okay, so you can drop dead"
Too bad for folks in South Korea and Japan

Furthermore, if you actually READ articles on NK, you will have read that they are developing missiles that could be launched from boats or submarines.  Oops, guess California just might not  be that safe after all.  

I guess, in conclusion, some prefer that we adopt a policy approach similar to that of Obama with Syria, wherein we draw a line in the sand with the use of chemical weapons, but when chemical weapons are used, we just pretend that nothing happened, and then we subsequently go off, stick our head in the sand like an ostrich, and pray that the problem goes away, while hundreds are killed in hospital bombings and millions of refugees are flooding into Europe.  I'm sure that pretty much sums it up, right?
