Massoud was a outstanding and capable military commander. As a politician it's negligable. He was receiving up to the day he was assassinated support from Russia and Iran, so you could see that as a win or loss had he became president. He might have been able to placate both countries to his side and maybe reduce animosity towards US forces there with their cooperation, or he might have sold out and asked them to be his allies and not the US. He was a man of honor and integrity, and hated the Taliban and Pakistan. Those two alone put him high in my book. At the very least he would have had the balls to basically say fuck you to Pakistan instead of getting on his knees like Karzai is doing. Doesn't matter anyhow, we're peace out of there before too long, long term we'll see what happens. Short of oil being discovered there the place will likely be like it was in the 90's in the international scale, "afghanistan? is that still going on?" to quote George H.W. Bush.
