NATO is a fundamental part of the international architecture used to further peace and prosperity in Europe  Peace has many foundations and no one international organisation can create all these foundations itself. NATO is therefore just as necessary to the peace of Europe as the OSCE or EU and all of these organisations need to expand to cover the states within Europe to promote peace. NATO therefore in its Message from Turnberry – its response to the end of the cold war - “express our determination to seize the historic opportunities resulting from the profound changes in Europe to help build a new peaceful order in Europe, based on freedom, justice and democracy.” [1] Collective defence is as necessary as economic cooperation in creating peace, this is something that in Europe only NATO can provide. Peace is also promoted by NATO through the security cooperation that it provides; building trust between the member states. This need for trust and equality between the parts of Europe was also explicitly stated by NATO’s Secretary General when he stated “Without enlargement, we would permanently frustrate the ambitions of countries of Central and Eastern Europe for inclusion in the transatlantic security and defence community. That would perpetuate an unnatural and potentially dangerous division between a prosperous, secure and self-confident West and an insecure and uncertain East.” [2] NATO enlargement helps heal this fault line and shows the cold war in Europe is really over.
