what was the purpose of nato and seato
Southeast Asia Treaty Organization SEATO was intended to be a Southeast Asian version of the North Atlantic Treaty Organization (NATO),[6] in which the military forces of each member would be coordinated to provide for the collective defense of the members' country. Organizationally, SEATO was headed by the Secretary General, whose office was created in 1957 at a meeting in Canberra,[7][8] with a council of representatives from member nations and an international staff. Also present were committees for economics, security, and information.[8] SEATO's first Secretary General was Pote Sarasin, a Thai diplomat and politician who had served as Thailand's ambassador to the U.S. between 1952 and 1957,[9][10] and as Prime Minister of Thailand from September 1957 to 1 January 1958.[11]
Warsaw Pact On 14 May 1955, the USSR and other seven European countries "reaffirming their desire for the establishment of a system of European collective security based on the participation of all European states irrespective of their social and political systems"[48] established the Warsaw Pact in response to the integration of the Federal Republic of Germany into NATO,[3][5] declaring that: "a remilitarized Western Germany and the integration of the latter in the North-Atlantic bloc [...] increase the danger of another war and constitutes a threat to the national security of the peaceable states; [...] in these circumstances the peaceable European states must take the necessary measures to safeguard their security".[48]
