President Reagan said in a recent interview that his comments in his March 8 speech in Orlando, Fla., casting the superpower arms race as a struggle between "good and evil," were lifted out of context by those who didn't hear the entire address.

Speaking to Henry Brandon, retiring Washington correspondent for the London Sunday Times, the president said of the Soviets: "Certainly, their entire beliefs . . . are so contrary to what we accept as morality. Witness a Kampuchea Cambodia and Afghanistan and so forth.

"But no, what I was pointing out there, and I still believe is time-tested and proven, is not the inevitability of war, but a recognition and a willingness to face up to what these differences are in our views and between us, to be realistic about it."

Reagan said that "under the guise of . . . detente" efforts were made to "sweep the differences between the superpowers under the rug." In Orlando, he said, "I stated, very frankly, what I believe the differences are, but at the same time, I have expressed my determination and my belief that peace is achievable.

"I am very concerned with those people who somehow seem to think . . . they are building in their minds that kind of 'war-is-inevitable' thing. I can't subscribe to that at all."
