Question: A country was in effective control of both political and military functions of the organization the People's Socialist Republic of Albania belonged. When did this country agree to a unified Germany inside the organization that killed Gaddafi's grandsons?

Knowledge 1: Muammar Gaddafi
A week after the implementation of the no-fly zone, NATO announced that it would be enforced. On 30 April a NATO airstrike killed Gaddafi's sixth son and three of his grandsons in Tripoli, though Gaddafi and his wife were unharmed. Western officials remained divided over whether Gaddafi was a legitimate military target under the U.N. Security Council resolution. U.S. Secretary of Defense Robert Gates said that NATO was "not targeting Gaddafi specifically" but that his command-and-control facilities were legitimate targets—including a facility inside his sprawling Tripoli compound that was hit with airstrikes on 25 April.

Horst Teltschik, Kohl's foreign policy advisor, later recalled that Germany would have paid ``100 billion deutschmarks ''if the Soviets demanded it. The USSR did not make such great demands, however, with Gorbachev stating in February 1990 that`` The Germans must decide for themselves what path they choose to follow''. In May 1990 he repeated his remark in the context of NATO membership while meeting Bush, amazing both the Americans and Germans. This removed the last significant roadblock to Germany being free to choose its international alignments, though Kohl made no secret that he intended for the reunified Germany to inherit West Germany's seats in NATO and the EC.

Hero of Socialist Labour () was an honorary title in Albania and other Warsaw Pact countries. It was the highest degree of distinction for exceptional achievements in national economy and culture. It provided a similar status to the title People's Hero of Albania that was awarded for heroic deeds, but unlike the latter, was awarded to citizens who contributed to the development of Albania's industry, agriculture, transportation, trade, science and technology and promoted the might and the glory of Albania. [SEP] Knowledge 4: Warsaw Pact
The Warsaw Treaty's organization was two-fold: the Political Consultative Committee handled political matters, and the Combined Command of Pact Armed Forces controlled the assigned multi-national forces, with headquarters in Warsaw, Poland. Furthermore, the Supreme Commander of the Unified Armed Forces of the Warsaw Treaty Organization which commands and controls all the military forces of the member countries was also a First Deputy Minister of Defense of the USSR, and the Chief of Combined Staff of the Unified Armed Forces of the Warsaw Treaty Organization was also a First Deputy Chief of the General Staff of the Armed Forces of the USSR. Therefore, although ostensibly an international collective security alliance, the USSR dominated the Warsaw Treaty armed forces.

During the 19th and 20th century, many national political parties organized themselves into international organizations along similar policy lines. Notable examples are The Universal Party, International Workingmen's Association (also called the First International), the Socialist International (also called the Second International), the Communist International (also called the Third International), and the Fourth International, as organizations of working class parties, or the Liberal International (yellow), Hizb ut-Tahrir, Christian Democratic International and the International Democrat Union (blue). Organized in Italy in 1945, the International Communist Party, since 1974 headquartered in Florence has sections in six countries.[citation needed] Worldwide green parties have recently established the Global Greens. The Universal Party, The Socialist International, the Liberal International, and the International Democrat Union are all based in London. Some administrations (e.g. Hong Kong) outlaw formal linkages between local and foreign political organizations, effectively outlawing international political parties.
