Answer:
The correct answer is D. The Soviet-Afghan War was like the Vietnam War for the Soviet Union.
Step-by-step explanation:
The Afghan-Soviet War took place between 1979 and 1989 between the Soviet Union (which supported the Marxist-Leninist government in Afghanistan) and the Afghan Islamic Mujahedin movement. The rebels were backed by the United States, which saw it as part of the Cold War. Already in 1978, an uprising against the Soviet-backed government that took power began. The uprising only worsened when the Soviet Union in December 1979 joined a large number of troops and occupied the country. As a result of the collapse of the Soviet Union, the regime in Afghanistan fell in 1992. In addition, a new civil war soon erupted between the phalanges that defeated the Soviet army.
