Imagine if Russia had pulled the same stunts Saudi Arabia recently has: bombing a small, poor neighbor into oblivion, murdering a journalist in an embassy. The uproar would be incessant and interminable, and there would sanctions on top of sanctions on top of sanctions. From Caitlin Johnstone at medium.com:

The US Senate has voted 56 to 41 to sorta-kinda eventually end America’s part in the Saudi-led war in Yemen, one step out of a great many that will need to happen in order to end the worst humanitarian crisis on the face of the earth.
The joint resolution still allows US drones to patrol Yemeni airspace and rain death from above in its “war on terror” against Al Qaeda, and it is unable to pass in the House this year due to an unbelievably sleazy rider that House Republicans attached to the unrelated Farm Bill. The resolution isn’t expected to change much in terms of actual US participation in the war besides some intelligence and reconnaissance assistance to Saudi Arabia and the United Arab Emirates against the Houthi rebels, since the US has already ended its assistance in refueling Saudi jets on their bombing campaigns as of last month. Trump is expected to veto any Yemen resolutions, and the Senate resolution was not passed with a veto-proof supermajority.
