The North Atlantic Treaty Organization (NATO) has been the most important and successful multilateral military political organization, pursuing the agenda of exporting democracy globally and ensuring the mutual defense of its allies. Historically, NATO was formed against the threat of communism emanating from USSR (Russia). The alliance did not use military option till the end of the cold war between the west and USSR, but post-cold war, it transformed and operated in Balkans, South Asia, Horn of Africa, and Middle East. The 9/11 incident further enhanced the military role of the organization and gave it ample reason to act internationally for ensuring the global security. NATO condemns in the strongest possible terms Russia's brutal and unprovoked war of aggression against Ukraine - which is an independent, peaceful and democratic country, and a close NATO partner. NATO and Allies continue to provide Ukraine with unprecedented levels of support, helping to uphold its fundamental right to self-defence.
