Prague underground was an underground culture developed in Prague, Czechoslovakia in the late 1960s and 1970s during the Normalization period. The movement was characterized by resistance against conformity, conventions, and consumerism. Because of its non-conformity, it had serious problems with the communist regime which considered it as a political opposition. <SEP> 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. <SEP> guilty of treason is a 1950 american drama film directed by felix e. feist and starring charles bickford, bonita granville and paul kelly. also known by the alternative title treason, it is an anti-communist and anti-soviet film about the story of józsef mindszenty, a roman catholic cardinal from hungary. mindszenty spoke out against the nazi occupation of his country during world war ii, as well as the later communist regime. because of his opposition to the soviet regime, mindszenty was arrested and tortured. after his release, he took refuge in the us embassy in budapest for many years, maintaining his support for the hungarians who wanted an end to the russian occupation. <SEP> In April 1969, Tito removed generals Ivan Gošnjak and Rade Hamović in the aftermath of the invasion of Czechoslovakia due to the unpreparedness of the Yugoslav army to respond to a similar invasion of Yugoslavia. In 1968, Tito offered Czechoslovak leader Alexander Dubček to fly to Prague on three hours notice if Dubček needed help in facing down the Soviets. <SEP> 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. <SEP> The army is also divided into major branches such as Air Defense Artillery, Infantry, Aviation, Signal Corps, Corps of Engineers, and Armor. Before 1903 members of the National Guard were considered state soldiers unless federalized (i.e., activated) by the President. Currently, the army is divided into the Regular Army, the Army Reserve, and the Army National Guard. Since the Militia Act of 1903 all National Guard soldiers have held dual status: as National Guardsmen under the authority of the governor of their state or territory and, when activated, as a reserve of the U.S. Army under the authority of the President.
