Saudi clerics preached extreme hatred of America to their students. Do they still do that? If so, why aren't Saudis on Trump's Muslim ban? Saudi citizens were the majority of 911 attackers. Why did the US invade Iraq instead of Saudi Arabia? I'll tell you the answer to all those questions. Oil and money! The royal theocratic rulers of Saudi Arabia bought the US many years ago, shortly after oil was discovered there in mass quantities. In exchange our politicians and military keep their mouths shut about the human rights crimes committed by the Saudi's while simultaneously criticizing other countries like Russia, China, Iran, Iraq, etc. for exactly the same behavior! Our hypocrisy has real life consequences! And we wonder why anyone would commit a terrorist crime against us or why groups like ISIS are so successful at attracting membership. If we expected the same behavior out of all of our allies instead being bought off by oil and money, the US would be trusted worldwide!
