Events in Yemen making headlines again to remind everyone that this now 8 year long war is still killing many innocent people and destroying the country. It's more complicated than what is going on in Ukraine with both Sunni Saudi Arabia and Shia Iran supporting different sides but the devastating effects on the civilian population is the same. Both sides are guilty of targeting civilians and of war crimes but I'm sure that a combined latent fear of an IS resurgence and increased need for oil won't see BJ being too critical of the Saudis on his visit.
