hmmm, if the South agreed and completes the THAAD installations it's a done deal taking out the North's nuke.
1) US travel ban to the North
2) THAAD installation complete
3) Kim Un ain't backing down
5) it's reported China has upped it's military border personnel to deter the North's refugees
4) theDonald/both Gov. Houses ain't letting the North join the Nuke Club

So complex wanting to protect the US homeland and the S.Koreans/Japanese may/will pay a price for it. Question I have, how many N.Korean artillery/rockets/missiles could the US and Allies knock out to start with? The THAAD system is part of that answer
