the revolutionary war
the war of 1812 (this is the first one that wasn't a true independence war, we tried to force Canada to join us.)
the civil war(this was a revolt not a war, the south was trying to retain slavery.
the first world war, we helped to keep Europe out of the hands of the Germans.
the second world war, again we helped to keep Europe out of the hands of the Germans, we also wanted revenge against japan.
the Korean war, we kept the south independent of the north.
the Vietnam war, we were trying to force freedom onto a group of people who really didn't want it.
the current war, the freedom to think the way we want to not have a small group trying to tell us how to think(small if you call 1.5 billion small). if you don't believe me then you haven't read the thread on the knighting of that writer.
this war is also a war of indecency from being attacked when ever the other group wants to do it.
