“If the device uses smuggled material, it will probably be used close to the border crossing, to reduce the chance of detection and interception en route to the target city.”
Insightful idea. The less such a device has to travel the less chance it will be detected. Of course the DoD/CD has nuclear detection set on high right now and every major port, city, and road is being closely watched. That doesn’t mean the bad guys won’t get super clever but when we refuse to watch who comes into this country I’d say the odds are real good that such a device could make it in, be assembled, and detonated. I mean, if the 9/11 operatives made it in just who the Hell are we turning away, anybody?
...yet another reason to move out of south San Diego County...
