Read the following excerpt from the address to the nation that Ronald Reagan gave in December 1987, after meeting with Mikhail Gorbachev of the Soviet Union. Select the two highlighted examples that show how Reagan-era policies contributed to the end of the Cold War.
a) On-site inspections and short-notice inspections will be permitted within the Soviet Union. Again, this is a first-time event, a breakthrough, and that's why I believe this treaty will not only lessen the threat of war, it can also speed along a process that may someday remove that threat entirely.

Indeed, this treaty, and all that we've achieved during this summit, signals a broader understanding between the United States and the Soviet Union. B) It is an understanding that will help keep the peace as we work toward the ultimate goal of our foreign policy: a world where the people of every land can decide for themselves their form of government and way of life.

Yet as important as the INF treaty is, there is a further and even more crucial point about the last 3 days and the entire summit process: Soviet-American relations are no longer focused only on arms control issues. They now cover a far broader agenda, one that has, at its root, realism and candor. C) Let me explain this with a saying I've often repeated: Nations do not distrust each other because they're armed; they are armed because they distrust each other. And just as real peace means the presence of freedom and justice as well as the absence of war, so, too, summits must be discussions not just about arms but about the fundamental differences that cause nations to be armed.

Dealing then with the deeper sources of conflict between nations and systems of government is a practical and moral imperative. D) And that's why it was vital to establish a broader summit agenda, one that dealt not only with arms reductions but also people-to-people contacts between our nations and, most important, the issues of human rights and regional conflicts.
