Defending our freedom

This came up recently, and I'm sure many times in the past, and I hoped we could expand upon it. A member here informed me that they were soon going to Iraq to defend my freedom. I argued that going to a foreign nation that we invaded and now occupy, even though they never attacked us and posed no threat, was not defending my freedom, and might even be jeopardizing my (and your) freedom. Anyone want to take this one up? Hopefully staying specifically on the subject of Iraq, and how it relates to our freedom.
