The Commander in Chief of Turkey’s half million-man military, President Recep Tayipp Erdogan, is a supporter of ISIS and a financial beneficiary of the ISIS oil trade. It is entirely reasonable to say that Turkey is aligned with ISIS and is actively supporting that group and other extremist jihadist groups in the attack on Syria. Image: Creative Commons
Since the start of the attack on Syria in 2011, Turkey has been a key transit point for foreign jihadists, supplies, and weapons headed for rebels fighting to bring down the Syrian government. Jihadists enter Turkey and get bussed to the Syrian border. Along the way, many are trained at facilities like that in Adana, Turkey. The Turkish military has done nothing to stop this.
The Turkish military did nothing in 2012 when local authorities in southern Turkey stopped a shipment of weapons to jihadists in Syria. When intelligence officials in Ankara instructed the local authorities to stand down and allow the weapons to pass to Syrian rebels, the army passively observed and silently endorsed the delivery of deadly munitions to jihadist extremists.
When the Syrian city of Kobani was under attack by ISIS in October 2014, the Turkish military lounged on their tanks in the hills above the besieged city and did absolutely nothing.
