The [Berlin] wall can disappear when those conditions that created it fall away. - Mikhail Gorbachev

Our first meeting in 1984 marked the beginning of a relationship that was difficult sometimes, not always smooth, but serious and responsible from both sides. Gradually, human relations developed as well, they became more and more friendly. Eventually we were able to reach mutual understanding, and this contributed to changes in atmosphere between our country and the West, and to the end of the Cold War. Margaret Thatcher was a great politician. She will remain in our memory and in history.

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 They derive from outdated notions about the nature of relations between our countries.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.

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.
