It's easy to sit here and say we'd never follow orders like the Nazis did had we been alive in Germany during WW2, or that we'd never own slaves if we happened to be a white landowner in Mississippi in 1843.

Given human nature, it's pretty amazing that the United States of America has survived all these 200+ years in the current form. I don't think many other nations can boast of such stable government over such a long period of time without a major revolution. It even survived the War Between the States. But I fear our time as a Republic is running out unless we elect leaders that will put us back on track.
