It's the world's biggest funder of terrorism. Saudi Arabia funnels our petrodollars, our very own money, to fund the terrorists that seek to destroy our people." So said Donald Trump, private citizen. But then President Trump made Saudi Arabia his very first foreign destination. Trump rode in a golf cart with King Salman, did a traditional sword dance and speechified about America's great friendship with "the Magnificent Kingdom." What changed Trump's mind? Apparently, $110 billion. That's how much the Saudis announced Saturday that they'll spend to buy advanced American weaponry - one of the biggest arms deals in history. This weapons deal, the president said, is all about U.S. jobs. Yet how many Americans want to work to arm the country that, as Citizen Trump said, "blew up the World Trade Center"? Fifteen of the 19 hijackers on 9/11 were Saudis. The 9/11 Commission report found that Saudi society "was a place where al Qaeda raised money directly from individuals and through charities," and that it was likely that "charities with significant Saudi government sponsorship diverted funds to al Qaeda." Massive amounts of funding still go from Saudi Arabia to extremist groups. The main force behind the weekend's arms deal is King Salman's son, Mohammed bin Salman. This young prince is leading Saudi's war in Yemen, where Saudi attacks on civilians have been flagrant enough to make the United Nations warn of war crimes.
