[340][341][342] In December 1987, Reagan and Gorbachev met again at the Washington Summit[343] to sign the Intermediate-Range Nuclear Forces Treaty, committing to the total abolition of their respective short-range and medium-range missile stockpiles.[344] The treaty established an inspections regime designed to ensure that both parties honored the agreement.[345] In May 1988, the U.S. Senate overwhelmingly voted in favor of ratifying the treaty,[346] providing a major boost to Reagan's popularity in the aftermath of the Iran–Contra affair. A new era of trade and openness between the two powers commenced, and the United States and Soviet Union cooperated on international issues such as the Iran–Iraq War.[347]
