The treaty was signed on April 4, 1949 in Washington, D.C. by a committee chaired by American diplomat Theodore Achilles. Previously, between March 22 and April 1, 1948, secret talks had taken place at the Pentagon, of which Achilles had declared: “The parties will consult each other if, in the opinion of one of them, the territorial integrity, political independence or security of one of the parties is threatened,” according to Article 4 of the official text of the Atlantic Treaty of 1949. which stipulates that any attack on a Member State is an attack on all Members and which also allows the use of armed force.

NATO Secretary General Rasmussen later stated, in the run-up to the October 2012 ministerial meeting, that the Alliance was ready to defend Turkey, acknowledging that this border dispute affected the Alliance, but stressed the Alliance`s reluctance to intervene: “Military intervention can have unintended consequences. Let me be very clear. We have no intention of interfering militarily [currently in Syria].  On the 27th. In March 2014, footage was posted on YouTube of a conversation allegedly involving then Turkish Foreign Minister Ahmet Davutoğlu, Undersecretary of State of the Ministry of Foreign Affairs Feridun Sinirlioğlu, then head of the National Intelligence Organization (MİT), Hakan Fidan, and Deputy Chief of Staff General Yaşar Güler.
It was reported that the recording was probably taken on March 13 from Davutoğlu`s office at the Ministry of Foreign Affairs.  Transcripts of the conversation show that the meeting not only considered options for Turkish forces conducting false flag operations in Syria, but also included a discussion of the use of the threat on the grave as a pretext for Turkey to intervene militarily in Syria. Davutoğlu said Erdoğan told him he saw the threat to the grave as an “opportunity.”  On the 26th. In July 2015, Turkey made the same request, given the gravity of the situation following terrorist attacks, to inform its allies of the measures it had taken. Poland invoked Article 4 on March 3, 2014 after tensions in neighboring Ukraine escalated as a result of Russia`s aggressive actions. Twice in 2012, Turkey requested an Article 4 meeting of the CNA: once on June 22, after one of its fighter jets was shot down by the Syrian Air Defense Forces, and the second time on October 3, when five Turkish civilians were killed by Syrian shells. Following these incidents, Turkey requested the deployment of Patriot missiles on November 21. NATO agreed to this defensive measure to help Turkey defend its population and territory and defuse the crisis along the border.
