"He also put in train a revision of the country’s foreign policy. Andropov quietly proposed that both the USA and the USSR should formally guarantee not to intervene militarily in the countries under their control. Thus he signalled disapproval of what had happened to Hungary in 1956 and to Czechoslovakia in 1968. Confidential indications were given to Cuba that the USSR was withdrawing its military guarantee for the island’s defence. He called not just for limitations on the superpowers’ stockpiles of nuclear weaponry but for their drastic reduction. Andropov, ex-Chairman of the KGB, understood that he would have a weak bargaining hand unless the USSR could show a sustained capacity to develop its military technology. The Politburo approved. Investment was sanctioned for upgrading the Soviet armed forces. The military-technological parity with the USA won by Brezhnev was to be reattained even at the expense of the popular standard of living. Andropov wanted to ‘perfect’ the communist order; he had hoped for plenty of time to do this. But Reagan’s geopolitical challenge would be met. The Cold War was going to get hotter."
