it that's why the past is never really past. this is a war that divided the country. when i hear people talk about how divided the country is today. it kind of makes me smirk in a way. this is the time 150 years ago when people, americans' brothers fighting brothers were killing each other. nearly 800,000 people now we think died in those four years of fighting. that's an astonishing number. 2% of the population. in other words, you are talking about 7 million people dying today. it was no city, no town no village that was unaffected by this war. and the after-effects lasted long, long after it was over. >> that's for sure. people's relationships the government totally changed. it was a looser con federation of states before the civil war and much more a federal system after. >> well, there is no question and when lincoln gives the gettysburg address which by the way anyone who wants to understand what it was really about read those 272 words. it only took him two minutes to say it.
