Do you think the American 'freedom' reasoning is overused sometimes?

I was watching Barack Obama on the news earlier and he was talking about the war in Iraq and how they’ve been fighting for American’s freedom. Maybe I’m looking at it from the wrong angle, but I don’t see how fighting a war in another country (with no-one invading yours) is fighting for freedom.

On British news, when they talk about out troops overseas, they approach it from the angle of us going over to help them or to protect interests, and other similar reasons. I understand why freedom is such a big part of American society, but do you feel it’s correct to say you’re fighting for freedom in Iraq or Afghanistan?

I truely hope I’ve worded this well as I really don’t want to offend anyone. I know a lot of these kind of questions are often meant as lighter fluid, but this isn’t intended to be.
