"If you did this as the first step towards the unleashing of war, well then, it is evident that nothing else is left to us but to accept this challenge of yours. If, however, you have not lost your self-control and sensibly conceive what this might lead to, then, Mr. President, we and you ought not now to pull on the ends of the rope in which you have tied the knot of war, because the more the two of us pull, the tighter that knot will be tied. And a moment may come when that knot will be tied so tight that even he who tied it will not have the strength to untie it, and then it will be necessary to cut that knot, and what that would mean is not for me to explain to you"
- Nikita Khrushchev
