If its that easy then most/all infrastructure is at risk.
This country is less than two weeks away from anarchy at any time.
Just finished reading a book titled Brave New War by John Robb. Came out in 2006 and therefore is heavily oriented toward the Iraq war. His main thesis is that small forces can and do target infrastructure and by so doing are able to defeat conventional armies as well as prevent them from winning the "hearts and minds" of the everyday citizens. Highly recommend it, although he gets a bit obtuse near the end.
I would say that if it ever gets to the point of civil war in this country, these are some of the tactics that will have to be employed.
