If there’s a civil war it won’t be Fallujah, it will be Somalia. I love our military but at some point, no matter how good, you are overwhelmed and outgunned. That’s why the miltary was so careful to keep the civilian population more or less on their side during Iraq.
They won’t be slimebag imported goat humping terrorists hiding IED’s and dialing a cell phone. You will have national guards and ex-military fighting and up against 1000 to 1 numbers or more, spraying and sniping. Many will be educated and use tactics, not running at you in a frontal assault to die for Allah. They will steal miltary equipment and even the odds. They will come at you from every direction
It won’t be on a flat desert, there will be many more cities, a much greater population, and much more territory to cover. You spread a million troops across this country and you’d barely know they were there. And everything you bomb is lost tax revenue - less money to pay the troops.
All that said, I don’t think the military will go there. Obama and crowd has far more to fear from our military than we do.
I appreciate what you say here, but secession is a political act, not an act of war. Don’t fall into that left wing trap. A seceding state(s) doesn’t ask for civil war, that would be insane. The seceding state(s) asks for their walking papers from the USA, if the Feds start something then....
