Most summits have a specific goal in mind, whether it is a peace treaty, arms negotiation, or trade. Many summits have alternate goals as well. These meetings are often used as an opportunity to get a feel for the other side and their points of view. Other times it is to make a statement to that nation, your own nation, or the world. Sometimes it is about making connections beyond the political ones.
The Moscow Summit was very much a Summit of alternate goals rather than substantive ones. President Reagan was determined to make a personal connection with everyday Russians. He wanted to help them understand the people of the United States and for him to better understand the hearts and minds of the Soviet people.
