Bomb their OWN cities to rubble?
Where I live that would mean bombing Washington DC to rubble, which would be 9-11 on steroids. They could not do this without killing their own paymasters. The Vietnamese talked of "grabbing Uncle Sam by the belt" meanign get close to neutralize air and artillery weapons. This still works today: they could bomb outlying neighborhoods but occupying rich neighborhoods by force would then provide automatic bomb shelters.

Hackers and GPS spoofing would redirect some of the PGM's from their intended targets to other targets preferred by the insurgents. Hell, even in Iraq and Afghanistan US air power was not able to stop insurgents armed with small arms, IED, and suicide bombers seemingly able to reach and take out targets at will. Air power is nothing but another kind of artillery, just as suicide bombers are. Hell, it can be argued that in Iraq, with warhead yields limted by proximity to pro-US forces, both sides had near artillery parity when all weapon systems are considered together.
I've actually considered the siege issue of cutting off food and how to counter it. In progressive communities here in DC there is already emphasis on urban gardening. If war was looming surely activists in many communities would warn of food security hazards not only from a siege but also from economic collapse. The latter commonly occurs in civil wars-and in the US could cause catastrophic food shortages affecting all sides. In fact, a city under siege with urban gardens might even have the edge over troops awaiting shipments of crops that might not be harvested or might not make it over roads swarming with their enemies. This is not new, in the old days some sieges were defeated by food shortages among the beseigers and who started out with the most food stored away would likely come out on top.
Lastly, don't forget that any civil war in the US would divide the US military, guaranteeing some access to the latest high-tech war toys to both sides. If this ever happens in the US, combinging this with ugly racial and religious hate could turn it into the bloodiest civil war outside the Congo (Congo has suffered 6 MILLION dead in fighting spurred by outsiders lusting for Coltan ore). The last civil war here was bad enough, losses were comparable to 1.2 million in today's population. Please do not hope that class struggle in the US devolves into a civil war on racial, religious, and regional lines-ask anyone in Iraq what THAT can lead to!
