Dust cutter, it is not good to raise panic but I have to tell you, I suspect that there may have  a plot to detonate an EMP over the midwest during the polar vortex. You will remember that we had extended RECORD COLD in the MIDWEST for an extended peiod, despite global warming. An atmospheric EMP over say Milwaukee or Chicago would have knocked out power for tens of millions of people in sub-zero weather. Millions would have frozen to death. There is no hard evidence of a plot; but a pretty fair amnount of circumstantial evidence.
