but does not follow through on cutting certain bilateral aid programs. The U.S. has been criticized for not maintaining a consistent policy; it has been accused of denouncing alleged rights violations in China while supporting alleged human rights abuses by Israel. However, some defenders argue that a policy of rhetoric while doing things counter to the rhetoric was necessary in the sense of realpolitik and helped secure victory against the dangers of tyranny and totalitarianism. The U.S. is advocating that Iran and North Korea should not develop nuclear weapons, while the U.S., the only country to have used nuclear weapons in warfare, maintains a nuclear arsenal of 5,113 warheads. However, this double standard is legitimated by the Nuclear Non-Proliferation Treaty (NPT), to which Iran is a party. Support of dictatorships and state terrorism The U.S. has been criticized for supporting dictatorships with economic assistance and military hardware. Particular dictatorships have included the Shah of Iran, Ferdinand Marcos of the Philippines, Somoza dynasty of Nicaragua, Fulgencio Batista of Cuba, Mobutu Sese Seko of Republic of the Congo, Emperor Haile Selassie of Ethiopia, Pervez Musharraf of Pakistan, Yoweri Museveni of Uganda, warlords in Somalia, Augusto Pinochet in Chile, Alfredo Stroessner of Paraguay, Carlos Castillo Armas and Efraín Ríos Montt of Guatemala, Jorge Rafael Videla of Argentina, Suharto of Indonesia, and Hissène Habré of Chad. Ruth J Blakeley and Vincent Bevins posit that the United States and its allies sponsored and facilitated state terrorism and mass killings on a significant scale during the Cold War. The justification given for this was to contain Communism, but Blakeley says it was also a means by which to buttress the interests of US business elites and to promote the expansion of capitalism and neoliberalism in the Global South. J. Patrice McSherry, a professor of political science at Long Island University, states that "hundreds of thousands of Latin Americans were tortured, abducted or killed by right-wing military regimes as part of the US-led anti-communist crusade", which included US support for Operation Condor and the Guatemalan military during the Guatemalan Civil War. According to Latin Americanist John Henry Coatsworth, the number of repression victims in Latin America alone far surpassed that of the Soviet Union and its East European satellites during the period 1960 to 1990. Mark Aarons asserts that the atrocities carried out by Western-backed dictatorships rival those of the communist world. Contemporary research and declassified documents
