Seemingly overnight the whole North Korea/Kim Jong-Un discussion is now the easily unhingeable despot may possess an actual hydrogen bomb. Think fusion not fission and over 10X the power of an A-bomb. If Kim can customize it for the nose of one of his ICBMs he can conceivably detonate it at a very high altitude thus causing a superpowerful electromagnetic pulse (EMP) completely destroying the US power grid. This whole thing reminds me of a bad Austin Powers movie.
