Thanks for the answers. If I understand correctly, if that country is our friend, we will be ok with their dictatorship (such as Saudi, Kuwait, ...) no matter what they do with their people; if that country is our enemy, we have to impose democracy on them, we have to impose sanctions on that country, we have to curse that country to death, ... . Is that correct ? I just wonder why my political science professor had never taught me this at college.
Also, please help me on this: If Saudi, Kuwait, ... are our friends, why don't they pump more oil to help reducing our gas price in this country ? If Saudi is our true friend, why does Saudi not allow us to station our troops in Saudi to support Iraq troops ?
