The decision was taken at the request of Germany and the Netherlands, the two states that led ISAF at the time of the agreement, and the nineteen NATO ambassadors unanimously adopted it.

This Treaty is ratified and implemented by the Parties in accordance with their respective constitutional procedures. Instruments of ratification shall be deposited as soon as possible with the Government of the United States of America, which shall notify all other signatories of any deposit.

At Turkey`s request, NATO has taken three collective defence measures: in 1991 with the deployment of patriotic missiles during the Gulf War, in 2003 with the agreement on a set of defence measures and the implementation of Operation Display Deterrence during the Iraq crisis and in 2012 in response to the situation in Syria with the deployment of patriotic missiles. The following twelve states signed the treaty, becoming founding members of NATO.
The following Heads of State or Government signed the Agreement as plenipotentiaries of their countries on 4 April 1949 in Washington, D.C: When Article 5 was drafted in the late 1940s, there was consensus on the principle of mutual assistance, but fundamental differences on how to implement this commitment. The European participants wanted to ensure that the United States would automatically come to the aid if one of the signatories was attacked; the United States did not want to make such a promise and managed to make it reflected in the wording of Article 5. This article is supplemented by Article 6, which provides that collective measures of defence are not only managed by events. NATO has a number of permanent active duty forces that make a lasting contribution to the Alliance`s collective defence efforts. These include NATO`s standing naval forces that are ready to act when called. They perform a variety of tasks, ranging from exercises to operational missions, in times of peace and in times of crisis and conflict.
