Ronald Reagan believed that schoolchildren in the US should be allowed the same religious privileges as Congress and the Supreme Court, such as prayer in school. His views on defense spending aimed to deter Soviet aggression and maintain peace through strength. Reagan brought in supply-side economics and reduced regulations on businesses and unions. In foreign policy, Reagan escalated the arms race with the Soviet Union and advocated aggressively for reducing communism and tearing down the Berlin Wall. However, some of Reagan's foreign interventions, like the Iran-Contra affair, occurred without proper Congressional consent.
