I didn't know Trump was going to attempt a coup on the United States government. Why didn't you nutjobs tell me?
OTOH, if Trump had succeeded in overthrowing the US government, the United States would have quickly splintered into groups. The US military would hold back and following the legitimate orders from government, not the Insurrectionists who overtook the government and murdered Pence and all the Democrats and Republicans who said anything bad about Trump.
I would hold back too, but if the government collapses, there would be chaos. The economy would be back to the barter system. Stores would become empty. If gangs of militia, KKK or some other assholes tried to take over, a lot of people would be killed.
Being proactive;
once the shooting started, and let me be clear on that point, I already identified a handful of houses in my area where I'd neutralize the head of the house and probably any other males over 10. War is a nasty business and most of these assholes have no idea what it's about or what it takes.
Every sane person on this forum, especially those who follow history, knows that a successful coup on the United States government by someone like Trump would fracture the United States. Some regions would erupt into war, some regions would war on others. Eventually Trump would end up like Mussolini or Qaddafi along with most of his family, but a lot more Americans would be dead than Trump caused by fucking up the COVID Response.
The good news is that I didn't have to kill anyone. Whew!

Trump failed, as did the other nutjobs, because our nation is a lot more resilient then the wackadoodles in the newz.
