who took the initiative to form the warsaw pact
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]
