North Korea says tested hydrogen nuclear device https://t.co/jqQ8YJd7YI — Reuters Top News (@Reuters) January 6, 2016

September 17th, 2015 during the second GOP debate at the Ronald Reagan Library. At 9:04pm Eastern Time Candidate Donald Trump became the only candidate, at any time, on any platform or debate stage, to mention the concerns with North Korea and nuclear weapons.

@54:28 …[…] and nobody ever mentions North Korea. Where you have this maniac, sitting there, and he actually has nuclear weapons. And somebody better start thinking about North Korea, and perhaps a couple of other places, but certainly North Korea. Ted and I have spoken, a lot of us have spoken, because we’re talking about Iran -and they are bad actors – bad things are going to happen – but in the meantime you have somebody right now in North Korea who’s got nuclear weapons, and who is saying almost every other week “I’m ready to use them”, and we don’t even mention it. ~ Donald Trump

The entire time Donald Trump is bringing up North Korea, candidate Jeb Bush is rolling his eyes and downplaying the concern. Watch the video again to see Jeb’s expressions.

The Next day -Again Four Months Ago- (Discussing Debate #2) Trump appeared on Sean Hannity show and emphasized the same concern. Watch:

We are aware of seismic activity on the Korean Peninsula & have seen claims of a nuclear test. Statement: pic.twitter.com/WvyFkpJcZo — WH National Security (@NSCPress) January 6, 2016
