Amen!!!
Beg to differ. Any almost universal revolt by the American people against their government, which includes the military, would be unable to "take over" as long as the military stuck by the government.
Such a widespread revolt might indeed make it very difficult for the government to enforce its will everywhere, perhaps impossible if the military would be unwilling to use extreme measures. But that's a very different issue from "the people" being able to defeat the government and its military.
Your statement would have been true up to about 1939, not since.
Since military men take an oath to the Constitution, not to the government, I don't get heartburn over this. I cannot imagine any issue that would divide the people sufficiently to lead to civil war that would not also divide the military. God forbid it ever comes to this.
