Final answer:
Conditions set by Reagan for better relations with the USSR included a reduction of arms, respect for human rights, and openness, leading to the INF Treaty and encapsulating the 'peace through strength' doctrine.
Step-by-step explanation:
Based on the excerpts provided from the 1987 State of the Union speech by Ronald Reagan and various accounts of his foreign policy, the conditions Reagan set for improved relations between the USSR and the United States included a reduction of arms, respect for human rights, and an overarching policy of openness in international affairs. This came after a series of diplomatic efforts by both Reagan and Soviet leader Mikhail Gorbachev, which included the signing of the Intermediate-Range Nuclear Forces (INF) Treaty. Reagan's approach to foreign policy also reflected the principle of 'peace through strength' which emphasized a strong military foundation for diplomacy, but there's no direct mention of requiring 'more responsible US conduct' or 'armed conflict' for improving relations.
