AFAIK DPRK hasn't complained about THAAD - so you're wrong there.
DPRK's "illegal" nuclear tests aren't "illegal", as they (and India and Pakistan) aren't signatories to the 1996 CTBT, and each have conducted tests since then.
I'm not arguing that DPRK is being "reasonable" - they're dangerous nuts.
But I'm hopeful that views such as yours don't prevail, as you've spent a few pages basically arguing that all hope is lost for negotiation, so acts of war are needed.
Where did I say NK complained about THAAD?
WHere did I say the nuclear tests were illegal?
A couple of posts above you state "NK says their banned nuclear tests"
They're actually not banned, DPRK hasn't signed the nuclear test ban treaty, so the USA whining about DPRK nuclear tests has the same validity as a NZ politician whining about US gun control.
THAAD doesn't actually solve anything - but it potentially P*(*)&ses the crap out of China, and China could actually be important if solving the real issue of KJU's lunacy is going to happen.
