Civl War: Our choosing of articles

I'm pretty shy person in class and I don't like to talk that much. I wanted to explain my articles here plus give an example of our todays war. I read two articles one from the North and one from the south. They both were attacking eachother about the causes of the war. North wanted Tariffs Slavery and state rights to be gone and the opposite goes for the South. While thinking of this I put it into todays standards and went out of the box for a little bit. I may go off topic but its something I wanted to share with everyone. The belief of slavery in the civil war was important but I don't belive that was the exact goal for united states to end it. I know it was important but everytime there is a war its always about money. In what I believe the underlying truth to the whole Civil War was Tariffs and State Rights. These both were hated by some politcal officals. They wanted a way to take them away because Tariff had to high taxes put on and State Rights wasn't exactly put well. Now comes something I wanted to discuss. Throughout the years there has been many wars and many issues. George Bush went to war because he wanted to defeat "Terror" which he thought Iraq had Nuclear weapons. That was a bullshit lie and people who believed it are dumb. The truth was he wanted to go after Hussien and his oil. People get manipulated by media so many times... Whats to believe anymore. Now I ask am I right or everything falls down by choice or by nature?
