Knowing the perverts I have met that are Saudi/Kuwaiti/Quatari and their customs - I do not think they would mind at all. You are almost as uptight as OBL. We are not Muslims. Those kids are Americans and they were off duty. After a year living in primitive conditions they are allowed to have some fun. I guess you have not seen some of the local establishments off base near most CONUS military bases - Most have a concentration of tittie bars within 2-3 miles of the main gate.
I don't have a problem with the drinking. I don't even have a problem with soldiers making visits to "tittie bars." These soldiers may have been off duty, but weren't they still on base? The females disrespected themselves in front of their fellow soldiers. It's not a threat to national security, but it is in poor taste. I guess I'm just an old stick in the mud on this issue.
