I said that wherever these people, meaning the Soviet leadership, confronted us with dangerous hostility anywhere in the world, we should do everything possible to contain it and not let them expand any further. I should have explained that I didn't suspect them of any desire to launch an attack on us.

I didn't think I needed to explain that, but I obviously should have done it.
