Effectively, Turkey is vowing to attack Syria. Since Syria allows/supports the Kurds attacking/remaining in the regions which Turkey and their FSA are attacking.
So NATO allows/enables this invasion of a sovereign nation, by Turkey with no authority.
It was not invited and was in the beginning done in the name of killing ISIS. Which does not resonate, since Erdogan is an Islamist and with Obama & Hillary armed and trained Al Quaeda and ISIS precursors. Until very recently
Turkey also made a deal with ISIS for control of Al Bab. They only held a small part of the city and were bogged down for months there.
In that deal it is said a ME Oil nation paid large sum of money and ISIS left (some of the ISIS simply changed badges and joint the Terrorist surrogates of Turkey)
This is a mess. Largely caused by Gulf Oil money, Obama, Hillary and Erdogan.
On assurances from some in the CIA and John McCain?
