<P0-S0> 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. <P0-S1> this was further fueled by cuban and united states intervention which led to a political polarization. <P0-S2> most south american countries were in some periods ruled by military dictatorships that were supported by the united states of america. <P0-S3> in the 1970s, the regimes of the southern cone collaborated in operation condor killing many leftist dissidents, including some urban guerrillas. <P0-S4> however, by the early 1990s all countries had restored their democracies. <SEP> <P1-S0> Currently, the army is divided into the Regular Army, the Army Reserve, and the Army National Guard. <P1-S1> The army is also divided into major branches such as Air Defense Artillery, Infantry, Aviation, Signal Corps, Corps of Engineers, and Armor. <P1-S2> Before 1903 members of the National Guard were considered state soldiers unless federalized (i.e., activated) by the President. <P1-S3> 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. <SEP> <P2-S0> The ZH-29 was a semi-automatic rifle developed in Czechoslovakia during the late 1920s, and used by the Chinese National Revolutionary Army. <P2-S1> The ZH-29 is one of the first successful self-loading rifles in service. <SEP> <P3-S0> a major consideration was the possible soviet reaction in the event that the us intervened. <P3-S1> the truman administration was fretful that a war in korea was a diversionary assault that would escalate to a general war in europe once the united states committed in korea. <P3-S2> at the same time, "[t]here was no suggestion from anyone that the united nations or the united states could back away from [the conflict]". <P3-S3> yugoslavia–a possible soviet target because of the tito-stalin split—was vital to the defense of italy and greece, and the country was first on the list of the national security council's post-north korea invasion list of "chief danger spots". <P3-S4> truman believed if aggression went unchecked a chain reaction would be initiated that would marginalize the united nations and encourage communist aggression elsewhere. <P3-S5> the un security council approved the use of force to help the south koreans and the us immediately began using what air and naval forces that were in the area to that end. <P3-S6> the administration still refrained from committing on the ground because some advisers believed the north koreans could be stopped by air and naval power alone. <SEP> <P4-S0> 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. <P4-S1> 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> <P5-S0> Because of its neutrality, Yugoslavia would often be rare among Communist countries to have diplomatic relations with right-wing, anti-Communist governments. <P5-S1> 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. <P5-S2> Yugoslavia also provided military aid and arms supplies to staunchly anti-Communist regimes such as that of Guatemala under Kjell Eugenio Laugerud García. <P5-S3> For example, Yugoslavia was the only communist country allowed to have an embassy in Alfredo Stroessner's Paraguay.
