In 1985, US Congress passes legislation requiring US economic sanctions on Pakistan unless the White House can certify that Pakistan has not embarked on a nuclear weapons program (see August 1985 and August 1985). The White House certifies this every year until 1990 (see 1987-1989). However, it is known all the time that Pakistan does have a continuing nuclear program. For instance, in 1983 a State Department memo said Pakistan clearly has a nuclear weapons program that relies on stolen European technology. Pakistan successfully builds a nuclear bomb in 1987 but does not test it to keep it a secret (see 1987). With the Soviet-Afghan war ending in 1989, the US no longer relies on Pakistan to contain the Soviet Union. So in 1990 the Pakistani nuclear program is finally recognized and sweeping sanctions are applied (see June 1989). [Gannon, 2005] Journalist Seymour Hersh will comment, “The certification process became farcical in the last years of the Reagan Administration, whose yearly certification—despite explicit American intelligence about Pakistan’s nuclear-weapons program—was seen as little more than a payoff to the Pakistani leadership for its support in Afghanistan.” [New Yorker, 3/29/1993] The government of Pakistan will keep their nuclear program a secret until they successfully test a nuclear weapon in 1998 (see May 28, 1998).
