These days, a CWII would be the most lethal thing man has ever witnessed. On the outset, it will be skirmished based with brief periods of negotiations. Eventually, there will be no ROE’s and “America’s” full arsenal will be brought down on the opposing force to “end CWII”. It won’t be a “north and south”; its going to be one giant kill box.
The standing Army of the USA is not large enough to conquer occupy one state, let alone 20. You have no idea the scope of what CWII would be.
Not hard to argue with that, but I believe if this comes to pass, it will be based on a betrayal by the Federal Government to pay the benefits it has promised to various demographic groups. Keep on eye on “social security reforms” or “Medicare reforms”. The first political battleground I see spilling over into organized civil disobediance will be the young vs. old (or more accurately, the working vs. retired). Simply put, the entitlements that the US Government pays to the retired are rapidly becoming a liability that cannot be serviced.
The elderly do not typically riot or burn down neighborhoods, but I could see some type of organized civil disobediance from senior citizens that are still relatively healthy, remembering the “hell no, we want go” days of their youth, and really PO’d at the rules of the game being changed when they are past the finish line or close to it.
The next phase would be ethnically based. A rural vs. city componnent could very well develop. The trigger to all of this will be economically based and once the lid blows off the pressure cooker of balkanized values, worldviews, demographics, economic realities, and yes, politics, it would be as bad as you say.
The spirit of entitlment that oozes through the pores of every member of this society will be its undoing once the gravy train stops rolling.
I don't see any need for fighting - probably. Obama is not terribly manly in any respect, and I can't imagine him initiating hostilities. So long as free Americans peacefully secede, I doubt that he would use force to stand in their way. We just have to make it perfectly clear that we do not support the initiation of violence, even in the face of leftist provocations designed to make it look like we are starting a shooting war.
