These leftists are such pests, they just never will be fit to live with. They believe that the truth is secondary to the cause, and that is why they must be crushed, eventually, by any means necessary.
You are quite correct that Gorby had his butt kicked. There was no way he could win.
However, I give him enormous credit for the way he lost. He most certainly could have ensured that the Soviet Empire collapsed in blood. In fact, it would have been quite possible for hundreds of million to have died during its fall.
I think sometime few of us really realize what a bullet we dodged there.
