paragraph_text: The strategy behind the formation of the Warsaw Pact was driven by the desire of the Soviet Union to dominate Central and Eastern Europe. This policy was driven by ideological and geostrategic reasons. Ideologically, the Soviet Union arrogated the right to define socialism and communism and act as the leader of the global socialist movement. A corollary to this idea was the necessity of intervention if a country appeared to be violating core socialist ideas and Communist Party functions, which was explicitly stated in the Brezhnev Doctrine. Geostrategic principles also drove the Soviet Union to prevent invasion of its territory by Western European powers.

paragraph_text: In Latin America in the 1970s, leftists acquired a significant political influence which prompted the right-wing, ecclesiastical authorities and a large portion of the individual country's upper class to support coup d'états to avoid what they perceived as a communist threat. This was further fueled by Cuban and United States intervention which led to a political polarization. Most South American countries were in some periods ruled by military dictatorships that were supported by the United States of America. In the 1970s, the regimes of the Southern Cone collaborated in Operation Condor killing many leftist dissidents, including some urban guerrillas. However, by the early 1990s all countries had restored their democracies.

paragraph_text: The East China Sea Air Defense Identification Zone (abbreviated ADIZ) is an Air Defense Identification Zone covering most of the East China Sea where the People's Republic of China announced that it was introducing new air traffic restrictions in November 2013. The area consists of the airspace from about, and including, the Japanese controlled Senkaku Islands (which are known as the Diaoyu Islands in mainland China and are claimed by mainland China as well as Taiwan) north to South Korean-claimed Socotra Rock (known as Suyan Jiao in China). About half of the area overlaps with a Japanese ADIZ, while also overlapping to a small extent with the South Korean and Taiwanese ADIZ. When introduced the Chinese initiative was controversial as requirements were imposed that other countries with air defense identification zones do not impose and it included contested maritime areas. Critics said the move escalated the Senkaku Islands dispute between China and Japan.

paragraph_text: After the Communist Party of China took power in 1949, the flag of China became a red flag with a large star symbolizing the Communist Party, and smaller stars symbolizing workers, peasants, the urban middle class and rural middle class. The flag of the Communist Party of China became a red banner with a hammer and sickle, similar to that on the Soviet flag. In the 1950s and 1960s, other Communist regimes such as Vietnam and Laos also adopted red flags. Some Communist countries, such as Cuba, chose to keep their old flags; and other countries used red flags which had nothing to do with Communism or socialism; the red flag of Nepal, for instance, represents the national flower.

paragraph_text: The Harmelen train disaster was the worst railway accident in the history of the Netherlands on 8 January 1962. Harmelen, in the central Netherlands, is the location of a railway junction where a branch to Amsterdam leaves the Rotterdam to Utrecht line. It is common at high-speed junctions to avoid the use of diamond crossings wherever possible — instead a ladder crossing is employed where trains destined for the branch line cross over to the track normally employed for trains travelling in the opposite direction for a short distance before taking the branch line.

paragraph_text: Because of its neutrality, Yugoslavia would often be rare among Communist countries to have diplomatic relations with right-wing, anti-Communist governments. For example, Yugoslavia was the only communist country allowed to have an embassy in Alfredo Stroessner's Paraguay. One notable exception to Yugoslavia's neutral stance toward anti-communist countries was Chile under Pinochet; Yugoslavia was one of many countries which severed diplomatic relations with Chile after Salvador Allende was overthrown. Yugoslavia also provided military aid and arms supplies to staunchly anti-Communist regimes such as that of Guatemala under Kjell Eugenio Laugerud García.
