Some countries supported a long-term agreement that would set its initial duration at 20 years, while others feared that anything beyond 10 years would be seen as an unnecessary extension of the war effort. Finally, at Portugal`s request, the treaty was validated for a period of ten years after which the treaty could be reviewed (Article 12); And it was only after the treaty came into force for 20 years that a member was able to withdraw from the organization (Article 13). To date, these two provisions have never been taken into account, i.e. the contract has never been audited or a member has never been removed from the organization. The North Atlantic Council (NAK) is NATO`s main political decision-making body. Each member country has an AK seat. It occurs at least once a week or whenever the need occurs at different levels. The Presidency is chaired by the Secretary-General, who helps members reach agreement on key issues.
NATO also has what it calls the membership action plan. It helps future members prepare for membership and meet the most important requirements by providing practical advice and targeted assistance. This treaty is ratified and its provisions are implemented by the contracting parties in accordance with their respective constitutional procedures. The ratification instruments are filed as soon as possible with the Government of the United States of America, which informs all other signatories of any filing. The treaty will enter into force between the states that have ratified it as soon as the ratifications of most of the signatories, including those of Belgium, Canada, Luxembourg, the Netherlands, the United Kingdom and the United States, have been tabled and will enter into force for other states on the date of the tabling of their ratifications. (3) Relations between the United States and the Soviet Union began to deteriorate rapidly in 1948. There were sharp differences of opinion on Germany`s post-war status, with the Americans insisting on the German takeover and possible rearmament, and the Soviets strongly opposing such actions. In June 1948, the Soviets blocked all ground travel in the American zone of occupation in West Berlin, and only a massive American airlift with food and other necessities supported the population of the area until the Soviets sank and blocked it in May 1949. In January 1949, in his State of the Union address, President Harry S. Truman warned that the forces of democracy and communism were mired in a dangerous struggle, and called for an alliance to defend the nations of the North Atlantic – the U.S. military in Korea.
In April 1949, representatives from Germany, Canada, Denmark, France, the United Kingdom, Iceland, Italy, Luxembourg, the Netherlands, Norway and Portugal joined the United States in signing the NATO agreement. The signatories agreed: “An armed attack on one or more of them… be considered an attack on them all. President Truman hailed the organization as a “shield against aggression.” On 23 September 1998, the UN Security Council adopted Resolution 1199 to call for a ceasefire to end Slobodan Miloévié`s action against Albanian separatists and civilians led by the KLA in Kosovo. Negotiations under U.S. Special Envoy Richard Holbrooke failed on 23 March 1999 and he handed the matter over to NATO, which, on 24 March 1999, launched a 78-day bombing campaign.  Operation Allied Force targeted the military capabilities of the former Federal Republic of Yugoslavia.
