It's the worst kept secret in the world. But it generally isn't said out loud. Those Muslim allies of ours, the ones Hillary Clinton claims that Trump's Muslim ban would alienate, are behind ISIS. So, according to her, we need the funders of ISIS to help us beat ISIS.
Democratic presidential nominee Hillary Clinton sent an email to her campaign chairman John Podesta in 2014, who was then-counselor to President Barack Obama, that said Saudi Arabia and Qatar are both giving financial and logistical support to the Islamic State and other extremist Sunni groups, according to a recent Wikileaks release.
“While this military/para-military operation is moving forward, we need to use our diplomatic and more traditional intelligence assets to bring pressure on the governments of Qatar and Saudi Arabia, which are providing clandestine financial and logistic support to ISIL and other radical Sunni groups in the region,” Clinton wrote.
So Hillary knows quite well who is behind ISIS. Covertly she talks about pressuring them. But in public, she lies to the people and tells them we must appease the backers of ISIS.
And it remains true that the path to defeating Sunni Islamic terror lies through Qatar and the Saudis and the rest of our "allies".
