In Afghanistan, the (Muslim) Northern Alliance was fighting the Taliban while the USA was negotiating with the Taliban to build an oil pipeline. Shia and muslim Kurdish militias have been spearheading the fight against ISIS. The deaths in these two wars run into hundreds of thousands of Muslims. 

Don't get fooled by the one western hostage beheaded by ISIS. There are thousands of Shiites and Yazidis and others executed for every one western hostage.
