If a Chinese plane landed at Los Angeles Airport having just bought down an American military plane, he wouldn't be permitted to leave the next day. So then we developed a framework which should have been acceptable as a concept to the Chinese, namely to express regret for the loss of life and maintain our position that we had a right to fly these missions.

The Gorbachev period is conceived as an abandonment of historic Russian positions. So this is the framework, in my view, in which Putin operates.

Let me make my point about Vietnam. When the Nixon initiation came into office, there were 550,000 Americans in combat. And ending the war was not a question of turning off a television channel. And so, debating on how we got there and what judgments were made was not going to help us.

I was always convinced that decent people in the case of Vietnam, highly intelligent, decent people, got us involved because they had made, in part, a misjudgment about the nature of the communist system and the unity of the communist world and the degree to which the experience of Europe could be repeated in Vietnam.

Even paranoid people have enemies.

To revolutionaries the significant reality is the world which they are fighting to bring about, not the world they are fighting to overcome.
