While the specifics of the federal counterterrorism strategy are classified, what is in the public record indicates that the plan contemplates having to deal with as many as three sites being simultaneously hit and using “overwhelming force” against the terrorists, which probably means mustering as many as 3,000 ground troops to the site. If that’s an accurate picture, it doesn’t bode well. We would most likely have far too few such elite units for dealing with a large number of small terrorist teams carrying out simultaneous attacks across a region or even a single city.

Nightmare possibilities include synchronized assaults on several shopping malls, high-rise office buildings or other places that have lots of people and relatively few exits. Another option would be to set loose half a dozen two-man sniper teams in some metropolitan area — you only have to recall the havoc caused by the Washington sniper in 2002 to imagine how huge a panic a slightly larger version of that form of terrorism would cause.
