They did the same with Libya, Egypt, Syria and others when those nations leaders would not get on board with their Global World Order Agenda. Quadafi prevented African migrants from coming through Libya, then sailing into Europe. After he was ousted, that door was open.
Assad is a secularist who protects Syria's Christians. Yet the Neocons' war on Assad sends a constant stream of (mostly Muslim) refugees into Europe.
Ousting the secular Saddam Hussein, who also protected Christians, further destabilized the region.
Pat Buchanan was right. All these Mideast wars are hurting Christians, empowering Muslim extremists, and sending millions of migrants into Europe.
You're post certainly referenced part of the reasons but they all are part of the Globalist agenda Reach of redistributing 3rd world populations into Western nations....obtaining control of nations resources, and implementing leadership in those nations agreeable to their Agenda for the World.....and equally as much all the various Faiths of the World under one control as a consistent revenue source and controlling the citizens through them.
