with AK's and homemade explosives Afghans have kept up the fight against our military for over a decade. Check the battle reports from Afghanistan. We still dying over there.
As I said in my post, this would be a military attack on home soil. Afghanistan is one of the worst places for any foreign military to fight due to the harsh terrain. That would not be an issue in the US, where you'd have familiar, easily exploitable terrain the US military is already familiar with; after all, they currently train in various bases in the US.
The military would suffer casualties but would have no problem snuffing resistance in an all out battle.
