Ronin, that's Conservative Spin.  The accurate fact is that NK carefully couches it's "destroy US" rhetoric basically with, "IF" US attacks, then we destory US.  
I don't think NK is saying, "we will attack for the fun of it."  That's the problem with what's going on right now.  Trump is giving NK every reason to believe the US is pursuing regime change.  
Basically, there is a lot of hate towards the US based on fear, emanating often from the existence of foreign governmental or radical approaches that conflict with US foreign policy and US interests.  Those not in line with the US view the US as a threat to impose its will upon them, and thus, a good part of the hate.
We tend to think, as a nation, that our way is right.  That our Judeo-Christian values are the "best", that our form of government needs to be imposed, that our economic interests are of forefront concern and that therefore we are justified in imposing international policies that pursue or protect those interests. . .
