If you mean the guy who apparently helped put the Taliban in power and gave Osama Bin Laden a base to launch the 9/11 attacks, yes.
From your posting on Dr. Wheeler, one could argue that Reagan's intervention in the Soviet-Afghan War lead directly to 9/11, ~3,000 civilian deaths, and an ongoing butcher's bill of US and allied troops that numbers in the thousands of dead and tens of thousands maimed.
Similar sentiment in some RINO and Democrat circles would have us oppose Putin in Syria, which would just be repeating the same mistake. In other words, if we stand in Putin's way, what Syrian-based mass casualty attack will be forthcoming in the coming decade or so?
Point to ponder in light of our Founder's strongly discouraging the US from getting involved with foreign wars. Such intervention has consequences.
