The commitment of government to deal with the population issue is of course essential....There are many ways to make the death rate increase.

I want to say, and this is very important: at the end we lucked out. It was luck that prevented nuclear war. We came that close to nuclear war at the end.

The indefinite combination of human fallibility and nuclear weapons will lead to the destruction of nations.
