Text of January 1958 address:

The threat to our safety, and to the hope of a peaceful world, can be simply stated. It is communist imperialism.

This threat is not something imagined by critics of the Soviets. Soviet spokesmen, from the beginning, have publicly and frequently declared their aim to expand their power, one way or another, throughout the world.

The threat has become increasingly serious as this expansionist aim has been reinforced by an advancing industrial, military and scientific establishment.

But what makes the Soviet threat unique in history is its all–inclusiveness. Every human activity is pressed into service as a weapon of expansion. Trade, economic development, military power, arts, science, education, the whole world of ideas–all are harnessed to this same chariot of expansion.

The Soviets are, in short, waging total cold war.
