Short answers, pulled from the story.
The Washington Summit of 1987 was a Cold War meeting between United States President Ronald Reagan and Soviet General Secretary Mikhail Gorbachev held on December 8-10 at the White House. Its most significant outcome was the signing of the Intermediate-Range Nuclear Forces (INF) Treaty, which eliminated shorter-range and medium-range missiles from both nations' arsenals.
The Intermediate-Range Nuclear Forces (INF) Treaty was signed at the Washington Summit on the 8th of December 1987. It eliminated an entire category of nuclear weapons rather than merely capping or limiting them, making it a landmark arms control agreement.
Reagan was dealing with the Iran-Contra scandal, stock market trouble, and the Senate's rejection of Supreme Court nominee Robert Bork in the period leading up to the summit. He also faced criticism of the INF Treaty from prominent conservatives including former President Richard Nixon, former Secretary of State Henry Kissinger, and commentator William Buckley.
Gorbachev faced domestic opposition to both his Perestroika reform programs and the INF Treaty negotiations. He had replaced more than 150 senior defense ministers and officers after the Mathias Rust incident, and just two months before the summit, Boris Yeltsin publicly denounced him and resigned from the Politburo in an unprecedented move.
Reagan and Gorbachev discussed human rights, emigration, arms control for chemical and conventional weapons, the status of START negotiations, the Strategic Defense Initiative, the Anti-Ballistic Missile Treaty, and regional conflicts in Afghanistan, Central America, Southern Africa, and the Iran-Iraq War. The summit also addressed Vietnamese withdrawal from Cambodia, the Geneva Agreements, and North Korea.
George P. Shultz served as Secretary of State during the Washington Summit of 1987. He met with Gorbachev in Moscow in late October 1987 to finalize the INF Treaty terms, and reported that the Soviet leader was unusually contentious during that session before quickly requesting that the summit be scheduled.
