The point to consider in a civil war is what is left of the country afterwards? Worst case scenario, the feds win and the nation is then made into a dictatorship. Best case scenario the feds lose and the nation is so devastated that we would actually be a 3rd world nation. Not to mention the reconstruction effort. You would have some that would want it to be a definitive Christian nation and others that would oppose that. The mistake we make is in thinking that everyone who opposes the joke in the Whitehouse agrees with us. They don't all agree with us and the diversity of opinion would make almost impossible to rebuild a nation. We haven't even discussed the issue of federal or state supremacy yet and you KNOW that would be a huge issue and like you said I don't see any Jeffersons or Monroes or Washingtons to take the reins of leadership and bring the country through it. Long story short, there would be no United States.
Well, I am a bit more optimistic. Yes it certainly looks like civil war is imminent, but it has looked that way before. If war comes, the leaders who would unite us are probably not yet known to us.
In 1775 who were the Monroes, Jeffersons, and Washingtons?
George Washington was a former commander of a militia (National Guard) regiment. In his 1 year of command at what would be a Lieutenant Colonel in our army today he had lost 1/3 of his men including 14 dead and 26 wounded in a friendly fire incident. He lost his commission in the Virginia militia in 1758 and applied for a commission with the British army but was turned down. In 1775 he showed up at the 2nd continental congress in uniform and ended up commander in chief.
Thomas Jefferson was a son of privilege and a wealthy lawyer and slave owner. The evidence is not clear that he may have fathered children with his slaves (certainly someone with similar DNA did but it could have been a brother or uncle). In 1775 he was a member of the state legislature and a lawyer, but hardly a national leader.
In 1775 James Monroe was a 16 year old land and slave owner who dropped out of his freshman year of college to join the 3rd Virginia Regiment. He did not become a state legislator until 1782.
My point is not to denigrate these founding fathers but simply to point out that there are potential leaders out there, we just have yet to hear about them. Extreme times will create great men.
