he was a victim of propaganda war between east and west. I remember voice of america was chanting a slogan how all these soviet intellectuals wanted to settle in america for freedom and was somehow true after seeing the trend. But he was the rare case where he denounce the sytem in US equivoacally as he did in USSR. His Haverd speech was booed by many participants  yet was a pinnacle conforming who ( east vs. west ) was rightous and  as much as he was welcomed & noised  after arrival in US as a propoganda war ( freedom blha blah) , his departure from this country was the most kept secret ( or lip tighted) from the western government or the free media. In another word, as much as his arrival at US was a big bang news his departure with reason was not for these western news gorrillas. Anyway if your're curious what part he was most disgusted in US ? it was pornography readily available everywhere here in the name of freedom.   RIP great soul !!!
