Final answer:
President Richard Nixon's main goal in his discussions and policies was centered on foreign policy matters. Although he was involved in environmental conservation and economic reforms, it was his initiatives in foreign relations, like the establishment of Détente and creation of the EPA, that stood out before the Watergate scandal overshadowed his presidency.
Step-by-step explanation:
The primary goal of President Richard Nixon's discussions and policies revolved around foreign policy, particularly relating to the Vietnam War and diplomacy with the Soviet Union under the policy of Détente. Nevertheless, Nixon's tenure was heavily marred by the Watergate scandal, a crisis that began with a break-in at the Democratic National Committee's headquarters and eventually led to Nixon's resignation. While Nixon did engage in environmental conservation efforts, such as creating the Environmental Protection Agency (EPA), it was foreign policy, and not environmental issues or economic reform, that was central to his discussions and initiatives. Despite his resignation due to Watergate, Nixon's foreign policy achievements included landmark discussions with China and the USSR, which had a lasting impact on international relations.
