“We used to say to the apartheid government: you may have the guns, you may have all this power, but you have already lost. Come: join the winning side. His Holiness and the Tibetan people are on the winning side.”

Advice given to her protégée, Kiron Skinner, while serving as Provost at Stanford University; quoted in James Mann, Rise of the Vulcans (Penguin Books, New York: 2004, ISBN 0-143-03489-8, p. 227.

This quote is widely attributed to Margaret Thatcher on various websites, and also appears in a number of books, including The Concise Columbia Dictionary of Quotations, Columbia University Press (1989), ed. Robert Andrews, p. 320 : ISBN 0231069901. 9780231069908 , but without any further source information such as date, location or any other context.
One valid Thatcher quote which may be the basis for the version above appears in the Second Carlton Lecture http://www.margaretthatcher.org/document/105799 (‘Why Democracy Will Last’), delivered at the Carlton Club, London (November 26, 1984) : Mr. Chairman, each generation has to stand up for democracy. It can’t take anything for granted and may have to fight fundamental battles anew. You know that marvellous quotation from Goethe : ‘That which thy fathers bequeathed thee / Earn it anew if thou would possess it.’
Thatcher also expressed this thought in a Speech to Atlantic Bridge (May 14, 2003) http://www.margaretthatcher.org/document/111266, delivered at the St. Regis Hotel, New York City : My friends, every generation has to fight anew the battle for liberty.

Introducing "Who by Fire"
Warsaw concert (1985)
Context: I come from a country where we do not have the same struggles as you have. I respect your struggles. And it may surprise you, but I respect both sides of this struggle. It seems to be that in Europe there needs to be a left foot and a right foot to move forward. I wish that both feet move forward and the body moves towards its proper destiny. This is an intense country; the people are heroic, the spirit is independent. It is a difficult country to govern, it needs a strong government and a strong union. … I would like to say to you, to the leaders of the left, and the leaders of the right, I sing... I sing for everyone. My song has no flag, my song has no party. And I say the prayer, that we said in our synagogue, I say it for the leader of your union and the leader of your party. May the Lord put a spirit, a wisdom and understanding into the hearts of your leaders and into the hearts of all their counsellors.
