This has gotten amazingly little press. In the hellhole that is Yemen, the Shiite militants have just successfully taken over the capital city, Sanaa (one of the oldest centers of Islam), and the Yemen president (a staunch ally of the US) has been captured by the militants. The US is sending warships to the area. http://www.washingtontimes.com/news/2015/jan/21/us-sends-navy-warships-into-red-sea-poised-for-emb/ People focus on Islamic State, but the reality is that Yemen is completely out of control, and now basically replicates the debacle to the North, being controlled by Shiite rebels, Al Qaeda Sunnis, and a brutal regime supported by the West and Saudi Arabia that is collapsing (well, pretty much collapsed yesterday) under the extremist assault. So much is coming back to haunt Saudi Arabia ... they are surrounded by nightmare extremists to the North AND the South now. The US cannot solve this problem for them. Either the Saudis step up to the plate, or they are going to get systematically dismantled by the extremists within and without their country.
