treaty not a legally binding treaty, but a political commitment that simultaneously came into force with the CFE treaty and served as a follow-up agreement. The commitment was that all signatories of the CFE Treaty would undertake steps to improve further confidence and security in the ATTU region. CFE-1A committed the 30 members of the treaty to establish manpower limits and, if deemed necessary, to reduce the existing manpower levels within the CFE area of application to reach these limits. The United States was limited under this commitment to have no more than 250,000 troops in the area of application. As an additional source of security assurance, the CFE -1A agreement required the parties to provide advanced notification of any increases made to the force levels.

While Russia partially withdrew troops and equipment from Georgia and Moldova, it did not do so completely as demanded by NATO. The linkage between the ratification of the adapted treaty and the complete withdrawal was a political decision made by NATO members based on fundamental principles of international law pertaining to the territorial integrity of sovereign states. Suspension and complete withdrawal by Russia After Russia was not willing to support the US missile defense plans in Europe, Russian President Vladimir Putin called for "moratorium" on the treaty in his April 26, 2007 address. Then he raised most of his points for rewriting the treaty during the Extraordinary Conference of States Parties to the Treaty on Conventional Forces in Europe, held in Vienna on June 11–15 at Russia's initiative. As his requests were not met during this conference, Putin issued a decree intended to suspend the observance of its treaty obligations on July 14, 2007, effective 150 days later, stating
