Then in 1969, I spent the spring term at Cornell University in New York. The invasion of August 1968 had already happened, but the hardline regime took several months to crack down on dissidents.

Nevertheless, there is another threat on the horizon. I see this threat in environmentalism which is becoming a new dominant ideology, if not a religion. Its main weapon is raising the alarm and predicting the human life endangering climate change based on man-made global warming.

As someone who lived under communism for most of my life I feel obliged to say that the biggest threat to freedom, democracy, the market economy and prosperity at the beginning of the 21st century is not communism or its various softer variants. Communism was replaced by the threat of ambitious environmentalism.

Other top-level politicians do not express their global warming doubts because a whip of political correctness strangles their voice.

I am afraid there are people who want to stop the economic growth, the rise in the standard of living (though not their own) and the ability of man to use the expanding wealth, science and technology for solving the actual pressing problems of mankind, especially of the developing countries.

But how can you speed up the transformation of society in a country as large as Russia? Those sounding the moral outcry are the ones who are trying to dictate their standards from the outside. Of course, that isn't the right way to go either. One cannot impose democracy from the other side of national borders, which is something we ourselves experienced during the communist era. The West's policies toward Eastern Europe, the Helsinki process - none of that really helped us.

My main concern is the political dimension of European integration. This is one of the most important issues of all, as far as I'm concerned. It has to do with our past, with our sensitivity, perhaps even our hypersensitivity in this regard.
