Remember back in March 2014 the Turkish Foreign Minister, Intelligence Chief and Undersecretary of Foreign Affairs were recorded in a meeting planning a false flag to attack their own troops from Syrian territory. In so doing they would then have a pretext to invade Syria and attempt to overthrow Assad.
This was posted on Youtube and Twitter which Erdorgan promptly blocked claiming the posting of said meeting was villainous and dishonest.
Erdorgan is absolutely a terrorist supporter and a total loose cannon.
The whole world knows Turkey is in bed with ISIS. It is a dirty well known secret.
