This Reddit analysis strikes me more as revolution porn than a revelation of actual government wargaming analysis, but nevertheless, it appears to be generally correct with regards to the essentials:
The United States Government has extensively studied the concept of second American Civil War. Their conclusion is as follows: They don’t have a snowball’s chance in Hell of winning. The moment civil war is declared, the government loses. No scenario or outcome ends in their success. Period. It’s just a matter of how long it takes.It would certainly make for an interesting wargame design challenge. And it also is in harmony with what we know of the Clinton adminstration's study of the various militia groups and the government's inability to suppress them. As a general rule, there is very, very little that governments can do about 4GW insurrections; a government that lacks the ability to suppress illegal organizations such as MS-13 and the Gulf Cartel isn't going to be able to do much about ideological rebels either.
A longer analysis will follow, but here are the salient points.
30% of the American population will actively revolt.
This alone is enormous and damning. Historically, you only need 10% of the population to actively participate in a rebellion to successfully overthrow the establishment: We only had 15% of the population actively attempting to throw out the British during the Revolutionary War; roughly 70% of what remained was neutral and simply stood by. By contrast, 30% of Americans in modern America would support a revolution to stop their own government if it happened tomorrow That’s how discontent the people are and how much the people don’t support the government.
The government would need infrastructure more than rebels would.
Already working with significant handicaps, the establishment would need electricity, access to the Internet, bridges, and airports to coordinate any active campaign against the rebellion. By contrast, the rebellion can work in the dark. Considering how easy it would be to sabotage US infrastructure, one of the first things the rebellion would do is collapse bridges, destroy, or seize power plants, and cover the Interstate in IEDs. This is relatively simple to accomplish, and it would inflict enormous damage on the establishment’s ability to restore order. It would also cost an enormous amount of time and effort to fix any sabotage, because the establishment would need to provide military protection to any workers attempting to rebuild, which is a drain their active fighting personnel resources that they could not afford.
