Why do we support Saudi Arabia?

i have recently traveld back from saudi arabia it is the worst country i have ever been to there is so much censorship all they ever show on telly is the king walking around kissing people and i mean all day. they have no oppision in goverment there are lots of people from third world countrys getting exploited like slaves working in poor conditions and nobody is allowed speak out for them. no information is allowed out of the country. it makes north korea look like a holiday camp.and the saudi people are not even allowed any infomation . every book i picked up in english had half the text cut out.but there are KFC's every place you go .
