We desperately need to recognise that we are the guests, not the masters, of nature and adopt a new paradigm for development, based on the costs and … - Mikhail Gorbachev

The essence of perestroika lies in the fact that it unites socialism with democracy and revives the Leninist concept of socialist construction both in theory and in practice.

I began my book about perestroika and the new thinking with the following words: "We want to be understood". After a while I felt that it was already happening. But now I would like once again to repeat those words here, from this world rostrum. Because to understand us really — to understand so as to believe us — proved to be not at all easy, owing to the immensity of the changes under way in our country. Their magnitude and character are such as to require in-depth analysis. Applying conventional wisdom to perestroika is unproductive. It is also futile and dangerous to set conditions, to say: We'll understand and believe you, as soon as you, the Soviet Union, come completely to resemble "us", the West.
No one is in a position to describe in detail what perestroika will finally produce. But it would certainly be a self-delusion to expect that perestroika will produce "a copy" of anything.

Frequently I have heard criticism and even accusations directed against me for my policy towards the countries of Eastern Europe. Some say that Gorbachev did not defend socialism in those countries, that he more or less 'betrayed his friends'. Others, on the contrary, accuse me for having been too patient with Ceaușescu, Honecker, Zhivkov and Husák, who had brought their states to the brink of catastrophe. I firmly reject these accusations. They derive from outdated notions about the nature of relations between our countries. We had no right to interfere in the affairs of our 'satellites', to defend and preserve some and punish and 'excommunicate' others without reckoning with the people's will.
