Do you really believe the "moral" reasons for war?

For example, when the president attacked Libya and told the public that it's for democracy, Qhadafi (sic?) is killing thousands of people, etc., so we must intervene and save the people. Do you really believe that's the REAL reason that we are in that conflict? I think it's more for a political agenda (as with all presidents), but that's just me. What do you believe?
