It would likely be a rough 3-4 year adjustment/recovery period but I'm skeptical about the extremely dire predictions which seem to be associated with a rogue EMP detonation. A coordinated sneak attack by a technologically sophisticated country with lots of military resources (such as China) could be a real nightmare. The rebuilding process in such a scenario would involve a lot more than the electrical/communications infrastructure. Hundreds, if not thousands, of nuclear retaliatory strikes would lay waste to about everything.
But if the false flag scenario is let loose - i.e. our own powers that be lets the EMP loose - no one to intercept...the usurper in charge has signaled - a couple-three years ago - that possibility, which seems to hint that it's on the agenda to present the 'need' for Martial Law - he said the 'the U.S. could withstand a nuclear event..."
