Yes they do.  We have given them to Japan for years.  They are off the books, but they are there.  
Yes, I do take out NKorea if they keep violating all of the agreements on blowing up nukes, shooting missiles over Japan, etc.  They are threatening us, Japan, and SKorea every time they speak.  That is enough to get rid of them in my book.  Besides that, your progressive liberal self ought to be enraged that NKorea is filling the atmosphere with radioactive plutonium and other deadly stuff that you hate.  Why don't you rail against that for a change, rather than b!t*h at Trump everyday in here for what he is doing to keep you safe?  Try that hat on for size or go hide in your cave under UH!  And don't feed the rats!
