This chapter examines the last two years of Leonid Brezhnev's life, shedding light on often ignored back channels between the superpowers. It describes the defense buildup that focused primarily on enhancing US nuclear forces, which Ronald Reagan had insisted were dangerously vulnerable to a Soviet first strike. It also cites how arms buildup benefited US allies, even if it occasionally entailed embarrassing public admonishments by Washington to increase their defense expenditures. The chapter illustrates the ideological warfare that occupied a newly important place under Reagan, who attacked the Soviet Union and its allies with apparent relish in public. It recounts US policymakers that congratulated themselves for finally putting the Soviet Union on the defensive, both militarily and ideologically, after just a year with Reagan in office.
