Defending the Soviet Invasion of Afghanistan

Looking back, even though I was a young Marxist at the time, I should have fiercely defended the Soviet invasion of Afghanistan.  Looking back, it was the right thing to do although badly executed.  Looking back, I fault the Soviet Union for not organizing an international force of communist and leftist volunteers to defend the communist government of Afghanistan at the time.  We would have been able to counter the band of religious fanatics and terrorists (like Bin Laden and company) who were armed and funded by the US and Saudi Arabia.  Hell, I would have volunteered for service in the international leftist cause at the time against the Saudi army of religious kooks.
