So.....Pearl Harbor was a conspiracy too? WTF?

I simply fail to see the point of arguing about old sh*t that's not going to make a difference now. If it turns out to be a conspiracy, then what? Are you going to overthrow the government because they can't be trusted? If it turns out to be true, then what? Probably won't accept it and argue about it anyway. It's all pointless blabbering to me.
