The big question is would the local operatives STILL operate if their home countries were turned into a cinder. If so it would prove nasty trying to catch them all.
For a guy who has not particularly been a militia-head, I am beginning to see why we do need our citizen militias back, double time. According to the first clause of the 2nd Amendment the militias will have to be answerable to their home states. (They'll have to coordinate with the office of homeland defense anyhow, or the state liaisons.) But get them going! I wonder why scenarios like this were not discussed on the zillions of 2nd Amendment threads here???
There were a few and all anyone got for their trouble was insults.
