Back then, as now, the Mohammedan groups are always shopping for nukes. The may bribe one away from Pakistan or Russia and then hide it in a freighter and when it pull into a U.S. port like San Diego or Bayonne...Boom. The aftermath would include some degree of an economic meltdown.
Yeah. Nukes.
And there are some other things they could do that might be more of a threat to our existence.
Yet, even nukes going off in a few places is not as much a threat to us existing as a nation as are the liberals who want to fundamentally change us.
Look at England. They are ceasing to exist and it has been completely of their own doing when liberals took over.
