I agree with most part. But, I think US has nothing to do with this sectarianism. Mullahs, and gulfies are the ones who ignited this sectarianism. I think everyone should have learnt a lesson which is, supporting a terrorist group would always back fire you in the future. Mullahs were very happy when these goons were creating problem for US, and they were supporting these goons, and now they are reaping the result. The same would happen for Saudis as well. About Taliban, you are wrong. They are not that much hostile about mullahs as you think. Now, USA, and Israel are only watching these animals slaughter each other, which is a good decision. USA should not spend tax money to save these goons, like Iraqis, who would later hate USA for saving them from their savage brethren.
