As NATO allies that are not in the European Union, Canada and Turkey share an interest in preserving the Alliance as the premier transatlantic body for defense dialogue and cooperation. On future membership, NATO as an institution must provide reasonable, pre-accession programs that strengthen security and encourage reform. Whether in the Balkans, Central Europe, Ukraine or Georgia, the Alliance should remain open to all those who share our values and are ready to contribute to Euro-Atlantic security. A number of well-established NATO nations were once themselves beneficiaries of the Open Door policy. We must remain open to membership aspirants and continue to reinforce the important role NATO has played in stabilizing relations in Europe, both during the Cold War and after, by extending the benefits of Alliance membership to others.
