Explanation:
Indirect Involvement in the Vietnam War
The Vietnam War, fought from the late 1950s to 1975, was a conflict that had significant global implications and involved several nations, particularly two dominant powers: the United States and the Soviet Union. While the U.S. supported the South Vietnamese government (the Republic of Vietnam) in its fight against communism, the Soviet Union provided support to North Vietnam, which was communist and aimed to unify Vietnam under a single government.
China also played a critical role by providing military and logistical support to North Vietnam, but in terms of the primary global powers, the clear division was between the U.S. and the Soviet Union.
Thus, among the options provided, the correct answer is the United States and the Soviet Union as the two global powers that were indirectly involved in the Vietnam War, each backing opposing sides in this heated conflict.
