Which intergovernmental military alliance signed in 1949 are Denmark and the Netherlands both members of?
NATO The North Atlantic Treaty Organization (NATO ; French: "Organisation du Traité de l'Atlantique Nord" ; "OTAN "), also called the North Atlantic Alliance, is an intergovernmental military alliance between several North American and European states based on the North Atlantic Treaty that was signed on 4 April 1949.
Baltic Entente The Baltic Entente was based on Treaty of Good-Understanding and Co-operation signed between Lithuania, Latvia, and Estonia on September 12, 1934 in Geneva. The main objective of the agreement was joint action in foreign policy. It also included commitments to support one another politically and to give diplomatic support in international communication. The endeavour was ultimately unsuccessful, as the combined strength of the three nations and their statements of neutrality were insubstantial in the face of the massive armies of Nazi Germany and the Soviet Union.
