What Rights?

In the national debate about dealing with Islamic terrorism, our troops fighting in Iraq are said to be defending our rights. First, when the term, troops, is used, images of the cavalry to the rescue are evoked. Second, the fighting has turned into a police action. Third, would someone please explain to me which of my rights are under attack in Iraq. I know full well that the Islamic terrorist wants to destroy western civilization, which would be bad for me and my family. But, what rights do Americans have in Iraq? What right do Americans have to be in Iraq? Oh, yes. I almost forgot, we are fighting the terrorists in Iraq so we don't have to fight them here in the good ole USA. If you believe the latter assertion, I guess you will believe that your rights are being defended in Iraq. Perhaps, it is time for some critical thinking.
