When Iceland signed the treaty in 1949, it did not have – and still does not have – armed forces. There are no legal obstacles to their training, but Iceland has chosen not to have one. However, Iceland has coastguards, national police forces, an air defence system and a voluntary peacekeeping force. Since 1951, Iceland has also enjoyed a long-standing bilateral defence agreement with the United States. In 2006, U.S. forces were withdrawn, but the defense agreement remains valid. Since 2008, the air police have been regularly led by NATO allies. Despite France`s withdrawal from NATO`s integrated military structure, two technical agreements have been signed with the Alliance, which defines procedures in the event of Soviet aggression. Since the fall of the Berlin Wall in 1989, France has regularly contributed troops to NATO military operations, making it one of the largest troop-contributing states. It is also NATO`s fourth largest contributor to the military budget. The Russian intervention in Crimea in 2014 led to harsh condemnation of NATO countries and the creation of a new „spearhead” of 5,000 troops on bases in Estonia, Lithuania, Latvia, Poland, Romania and Bulgaria.  At the ensuing Wales Summit in 2014, nato heads of state or government formally committed for the first time to devote at least 2% of their gross domestic product to defence by 2024, which was previously only an informal directive.
 NATO did not condemn the clean-up in Turkey in 2016.  NATO members opposed the UN Treaty on the Prohibition of Nuclear Weapons, a binding agreement for negotiations on the total elimination of nuclear weapons, supported by more than 120 UN.  Lord Ismay`s leadership qualities were seriously tested during his tenure. When he took office, some allies had been fighting in Korea since 1950, when the pro-Soviet north crossed the 38th parallel to the pro-Western south. General Eisenhower, SACEUR since April 1951, was already traveling through the Allied countries and asking for financial and military assistance to create an integrated military structure and build NATO`s military capabilities if the Soviet Union decided to expand its influence in Europe. General Eisenhower needed Lord Ismay`s support to convince war-torn countries to make even more sacrifices for defense efforts. In 1956, Lord Ismay was also to play the role of Secretary General, while his country and France openly disagreed with the United States over the Suez Canal. Thus, the first five years of the Alliance were rich in events and Lord Ismay had the foresight to record them. His first five years of NATO – 1949-1954 ” were the first public recording of NATO. On 16 December 2002, the European Union (EU) signed a comprehensive set of agreements with NATO within the framework of the Berlin Plus Agreement.
This agreement gave the EU the possibility to use NATO funds in case it wanted to act independently in an international crisis, provided that NATO itself did not want to act – the so-called „right of pre-emption”.  For example, Article 42(7) of the 1982 Treaty of Lisbon provides that „if a Member State is the victim of armed aggression on its territory, the other Member States are obliged to provide assistance and support by all means at their disposal”. The treaty applies worldwide to certain areas, while NATO is limited, in accordance with Article 6, to operations north of the cancer reversal circle. It offers a „dual framework” for EU countries that are also linked to the PfP programme. [Citation needed] The alliance has shown unity: on 16 April 2003, NATO agreed to take command of the International Security Assistance Force (ISAF), which included troops from 42 countries. The decision was taken at the request of Germany and the Netherlands, the two nations that led ISAF at the time of the agreement, and all nineteen NATO ambassadors unanimously approved it. .
