What is the main argument of Reagan's 'Evil Empire' speech? Why do you think Reagan chose to speak about the Cold War in an address to a religious group?

The main argument of Reagan´s "Evil Empire" speech to the National Association of Evangelicals (1983) was to urge people to refuse the nuclear freeze proposals that were being debated in Congress with the support of the Soviet Union, to prevent Reagan´s "peace through strength policy" from furthering the United State´s military intervention in Europe.

Explanation:

Having met the day before with conservative leaders and pro-defense officials to discuss the nuclear freeze, according to the President's National Security Advisor Judge William Clark, Reagan was urged to address the subject publicly more often. That´s why he added content to his speech that accused the Soviet Union of being an “evil empire” and presented the issue as a good versus evil matter, with plenty references to God to appeal to the religious congregation into his doctrine.
