I wasn't that worried about it until I saw a video of him casually talking about nuking hurricanes to try to bust them up, at which point I was, like, OMG WTF!??!? and after that I was much more concerned, since he clearly had no clue about radioactive fallout or ANYTHING and, yeah... it became an active concern.

*deep breath*

I'm still worried about the North Koreans, but at least on OUR side we no longer have a child ruler who thinks nukes are a fun toy.
