The correct answer is B. Providing weapons to rebels fighting to overthrow a foreign communist government would be more likely under the Reagan Doctrine that under the foreign policy of detente.
Explanation:
The Reagan Doctrine was a Cold War foreign policy doctrine of President Ronald Reagan, by which the United States sought to diminish the international influence of Communists. Although the doctrine was followed for less than a decade, it was at the heart of US foreign policy from the early 1980s until the collapse of the Soviet Union in 1991.
In practice, the doctrine meant US assistance to anti-communist guerrilla and resistance movements in countries supported by the Soviet Union in Africa, Asia, and Latin America. Its purpose was to reduce the influence of the Soviet Union and to create the conditions for capitalism and democratic governance. For example, support was given to Contra-guerrillas in Nicaragua and Islamist Mujahden-guerrillas in Afghanistan.
