From The New York Times:
http://www.nytimes.com/2015/03/26/wo...his-yemen.htmlSaudi Arabia announced on Wednesday night that it had begun military operations in Yemen, launching airstrikes in coordination with a coalition of 10 nations.
The strikes came as Yemen was hurtling closer to civil war after months of turmoil, as fighters and army units allied with the Houthi movement threatened to overrun the southern port of Aden, where the besieged president, Abdu Rabbu Mansour Hadi, has gone into hiding.
Just as had been the case with Bahrain, it appears that Saudi Arabia and neighboring states may have drawn a line on preventing Shia movements from toppling governments in adjacent states. The Gulf Cooperation Council's military intervention to quash a Shia uprising in Bahrain very likely deprived Iran from gaining an ability to blockade the Persian Gulf, a development that could have facilitated Iran's drive for regional hegemony. Whether or not Saudi Arabia and its regional alies send ground forces into Yemen to restore order after using air power to degrade the Houthi militants remains to be seen. If they do, not only will such a development hold the possibility of strengthening regional stability, but it could also signal a new more assertive national security doctrine on the part of Saudi Arabia and its regional allies.
