Also, huge numbers of our military would refuse to fight a war against their own citizens. I suspect that a lot of military equipment would fall under civilian control that way.
It really doesn’t matter. It’s just mental acrobatics at this point anyway.
So you’re relying on the fact that the soldiers who you’ve been blowing up and shooting at will want to join your side? That’s a massive ‘if’, and if you’re relying on them joining you and bringing their equipment with them, doesn’t this make the second amendment a moot point?
Also, what makes you think that the entire citizenry would be on your side? Lets take the example of the War of Independence, which was also essentially a civil war between loyalists on the side of the government and the rebels.
The technology available at the time meant that a rebel force could equip itself to something approaching an equal standard to government forces, in the case of rifles, even better, and was capable of defeating a government force conventionally in the field in the right circumstances. Even then though, without French assistence, especially naval support, the rebels had next to no chance of actually being able to trap and destroy a government army and thus bring the war to an end.
This was less the case during the American civil war, but in that case, the rebels still put up a good fight before the superior equipment available to the Union told against them.
Nowadays though, the disparity is huge. It may have been feasible a couple of centuries ago for a citizen’s militia to get some horses and cannons, but getting tanks and helicopters/jet fighters etc is just not feasible.
Sure, a rebel force may be able to inflict a few casualties like they are in Afghanistan, but the casualties are going to be a lot greater on your side, and as for any dreams of defeating a government army in the field and driving it away so you can storm Washington DC and overthrow the government, forget it. Not going to happen. Best you can hope for is to survive for a long time until everybody gets sick of fighting and the government is prepared to make a few token concessions to you to allow you to keep some of your pride intact as you surrender yourselves and go back to a peace were it is unlikely you will have achieved anything meaningful for your efforts...
