A lot of union soldiers died for Lincoln's and your belief in the first civil war. If the president of the US at the time of the next secession believes that statement, I can guarantee that a lot more are going to die for that misguided concept in the next civil war.
“We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness. That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed. That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute a new Government,” Declaration of Independence
I have no experience as a warrior or soldier and am past the age of hand to hand combat. But as a pathologist, I have over thirty years of experience in determing why people died. I have personally performed over one thousand autopsies. What kind of an enemy would I make? No, I don't think I would be using missiles or tanks. Bombs and guns? Not likely. No, I think my personal choice of weapons would be chemicals and biologicals.
