"Q: You recently said, not referring to socialism in general but to the USSR in particular, that socialism had been assassinated, stabbed in the back. In this conspiracy of daggers that killed socialism, would you say Gorbachev was one of the assassins? A: No, I could not say that about Gorbachev because I have another view of Gorbachev and it is not one of an assassin who plotted the USSR's destruction. The USSR self-destructed in an incredible way. The responsibility for that self-destruction undoubtedly lies in the hands of the country's leaders, those who led that nation. Now, some of them were aware they were destroying it and others were not. That is what I was trying to say, more or less, and we saw it all from the beginning. I cannot say Gorbachev played a role in which he was aware of the destruction of the USSR because I have no doubt that Gorbachev intended to fight to improve socialism."
