In 1970s Afghanistan was a communist state. The leader Nur Mohammed Taraki was much like a puppet of the Soviets. When the policies (education, land distribution etc.) initiated by the Soviets proved to be unsuccessful, the Mujahideens (Islamic Soldiers) fought with the Afghan army which is what we know as The Soviet War.
Now...my question is that Afghanistan was surrounded by Iran and could be a better way to reach the Persian Gulf and also the discovery of oil in 20th century was a major source of "lust" to the Super Powers especially Soviets and the US then why the Soviet Leader refused to help Afghan Allies in the war against the Mujahideens? Why did the Soviets let such an important state go?
Was it a part of strategy? Was the US intervention irritating them and making them feared?
Or they were just enjoying the barbaric show...the very famous policy prevalent nowadays "let them fight and die...we'll just enjoy the show and when the right time will come we will grab the opportunity and then will become heros of the nation"??
