I’m not sure what they thought they were gaining by moving out of there in the first place.
But, good to see that NORAD is content that Obama has made the world a safer place. Yep, they appear completely content with the Russian reset. They seem to be not at all worried about the Iranians or North Koreans firing an EMP device from a container ship. Whew, now I can sit back and relax knowing that the government will secure the borders, protect me and take care of me.
There are three types of potential EMP originating from a nuclear explosion. The worst requires a very high altitude burst that excites the atmosphere and creates a very widespread, fast-acting, high energy pulse. The other two which would be more likely from a scud-like missile capable of fitting in a shipping container, and thankfully tend to be area-effect weapons with much more limited range.
Sure they would screw up the coastal cities but the entire country would not descend into the 11th century. At least not immediately.
Best to read up on HEMP and SHREMP. Learn the difference; but it’ll all ruin your day.
