Excerpts from Books and Wikipedia
"Determined to erase feudalism, the PDPA [Democratic Party of Afghanistan] road roughshod over the religious sensitivities and traditions of rural Afghans. And Islamic backlash soon reduced the country to chaos, and it looked like the PDPA was unlikely to survive." [Furtado: 1001 Days] "The Soviet war in Afghanistan was a nine-year war during the Cold War fought by the Soviet Army and the Marxist-Leninist government of the Democratic Republic of Afghanistan against the Afghan Mujahideen guerrilla movement and foreign "Arab–Afghan" volunteers. The mujahideen received wide military and financial support from Pakistan, also receiving direct and indirect support by the United States and China. The Afghan government fought with the intervention of the Soviet Union as its primary ally." [Wikipedia]
