Which statement accurately describes the reason the Soviet Union invaded Afghanistan

Answer 1

The Soviet Union invaded Afghanistan in December 1979 primarily to support the communist government of the People's Democratic Party of Afghanistan (PDPA), which was facing increasing resistance from insurgent groups known as the Mujahideen. The Soviets aimed to stabilize the Afghan government and prevent the spread of Islamic fundamentalism, which they feared could inspire similar uprisings in neighboring Soviet republics. Additionally, Afghanistan's strategic location was important to Soviet interests in the region. This invasion marked the beginning of a lengthy and costly conflict for the Soviet Union, often referred to as the Soviet-Afghan War.
