To determine the correct answer for this question, let's break down the options and analyze them:

a. Abandoning realpolitik, or practical politics: This is not considered one of Nixon's greatest accomplishments. Realpolitik is a political philosophy that focuses on practical considerations rather than ideology, and there is no evidence to suggest that Nixon abandoned it.

b. Bringing about détente with the Soviet Union and with China: Détente refers to the easing of tensions between nations. This is considered one of Nixon's significant accomplishments, as he played a crucial role in establishing more peaceful relations with both the Soviet Union and China.

c. Establishing the People's Republic of China: Although Nixon played an important role in normalizing relations with China, he did not establish the People's Republic of China. The People's Republic of China was established in 1949.

d. Ending the Vietnam War with a resounding American victory: This statement is not accurate. The Vietnam War did not end with a resounding American victory. In fact, the war ended with the Paris Peace Accords in 1973, and the United States eventually withdrew its forces from Vietnam.

Based on this analysis, the correct answer is b. Bringing about détente with the Soviet Union and with China. Nixon's efforts to improve relations with these two major world powers were regarded as one of his major achievements in foreign affairs.
