MY! I would never ever have thought this would ever be possible!

The US has always vaunted the preciousness of its democracy.

However, the evidence does not support this vaunting:

Its population is the most armed of all nationals in any country in the world.
In a coup in the US, you can see the spark for a civil war. 

A coup will be staunchly seen as an utterly illegal violation of the US constitution; and this will be balanced by those 30+% who now can see the validity for a coup.

Armed as each side are, when it takes place, the inevitable will follow.

If it does not, then the US will have a taste of the kind of military dictatorship that was its delight via its CIA to put on top of so many countless nations of the world.

Just as politicians as a life form are know to be hopeless at running the countries they are elected to do in, the military as a life form are even worse at the task.
