Well, the Civil War and the Monroe Doctrine are different beasts, I suppose comparing Lincolns civil war policy with the Monroe Doctrine is more on the same footing, but heck, I think Monroe Doctrine has a strong running. I mean, Civil War was about whether the Federal Government would control the southern states. Eventually, states may have entered the union, or states may have left, but we still would have had the near 50 states, united or not. If Europe had been allowed to colonize and take over, it would be a completely different continent. So I think I'll go with Monroe Doctrine. What about the doctrine itself, how did Monroe get it together and why?
