This article was written for people like you. Not much of a real thinker. Stop trying to blame any Administration. North Korea has been a pain before Bush or Obama. Matter of fact they been a thorn since (Yes!) the Reagan years. Recently, we watch in the news that North Korea has been testing and they just found out they have the ability to reach
Japan or maybe to Guam. Now this article is suggesting that North Korea has the power and accuracy to hit a power grid. In school, didn't your teacher tell you to read and then think about what you read. Some truth is in here as well as a hell of a lot  of a exaggregation to scare you. So that you would do exactly, what you did blame Bush and Obama This propaganda  is so that you would put your blind faith in Trump. (Which is scarier than the article).  Please read more and Have a bless day.
