NK is constantly threatening to nuke it's neighbors & America, now they actually have 10-30 nuke bombs to do it.
If we'd have bombed them in the last 10 years they wouldn't have the nukes they have now. They need to be stopped from creating more. Period.
"The latest Chinese estimate that North Korea could have 20 warheads today and 40 by 2016, reported exclusively by the Wall Street Journal on Thursday, surpasses that of most U.S. experts. The current U.S. Congressional estimate is that North Korea has 10-16 nuclear weapons. Apr 23, 2015"
