I know too many members of the US military to think that they would ever support a coup by any group. Every tyranny uses fear to control the majority. While democracies are perfectly capable of oppressing minorities they do not oppress the majority.
History is a series of cycles, just because our current cycle seems to be in the wrong direction does not indicate where the long-term trends are heading. I have faith in our country and in the future of mankind.
There was an interesting article posted earlier today The Great Patriotic War with the following quote.
After the war, Robert E. Lee faced both defeat and personal hardship, yet his faith burned as strong as ever, as we see in these words:
"My experience of men has neither disposed me to think worse of them; nor indisposed me to serve them; not in spite of failures, which I lament, of errors, which I now see and acknowledge, or of the present state of affairs, do I despair of the future. The march of Providence is so slow, and our desires so impatient, the work of progress is so immense, and our means of aiding it so feeble, the life of humanity is so long, and that of the individual so brief, that we often see only the ebb of the advancing wave, and are thus discouraged. It is history that teaches us to hope."
