Glassboro Summit Conference

The Glassboro Summit Conference, usually just called the Glassboro Summit, was the 23–25 June 1967 meeting of the heads of government of the United States and the Soviet Union—President Lyndon B. Johnson and Premier Alexei Kosygin, respectively—for the purpose of discussing Soviet Union–United States relations in Glassboro, New Jersey. During the Israeli-Arab Six Days War diplomatic contact and cooperation increased, leading some to hope for an improvement in the two countries' relations. Some even hoped for joint cooperation on the Vietnam War. Although Johnson and Kosygin failed to reach agreement on anything important, the generally amicable atmosphere of the summit was referred to as the "Spirit of Glassboro" and is seen to have improved Soviet–US relations.

With the United States gradually losing ground in the Vietnam War, the administration was looking for other solutions to the conflict.

On 5 June 1967 the Six-Day War began between Israel and the Arab states. The war led to an increase in Soviet-US diplomatic contact and cooperation; there were some who hoped this could continue to help the US solve the Vietnam war and other pressing international issues. On June 10, 1967 Premier Alexei Kosygin wrote a letter to contact President Lyndon B. Johnson. The “hot line” message arrived at the White House to seek communication between the United States and the Soviet Union. Alexei Kosygin gives a quick explanation of what the Soviet Union and United States should do in regards to the Middle Eastern Crisis. In the message Alexei Kosygin writes:

"To The White House

To President Lyndon B. Johnson

Dear Mr. President:

The events of the last days have forced me to express to you with all frankness our view. As the situation shows, the resolutions of the Security Council are invalid. Israel has completely ignored them. As you can understand, after the many attempts taken in this direction and the resolutions of the Security Council concerning the termination of aggression on the part of Israel in the Near East - - these attempts have proved ineffective.
