Lyndon Johnson actually said...

Nice words and solemn warnings of rhetoric won't stop an aggressor or a guerrilla or a Communist.

We are out here to learn about testing new fuels, new materials, new approaches to old problems, new forms of public and private cooperation...

Nor, may I say, do we have a different face for Moscow, Peking, or Hanoi.

Those were the problems that met me when I first went to Washington.
