U.S. Senator Robert Taft—one of the subjects of John Kennedy’s book Profiles in Courage—made this speech opposing the North Atlantic Treaty on July 26, 1949:
Why did I vote against the Atlantic Pact? I wanted to vote for it—at least I wanted to vote to let Russia know that if she attacked western Europe, the United States would be in the war. I believe that would be a deterrent to war…. We issued just this warning in the Monroe Doctrine, and though we were a much less powerful nation, it prevented aggression against Central and South America. That was only a President’s message to Congress, and there were no treaty obligations, and no arms for other nations. But it was one of the most effective peace measures in the history of the world. I would favor a Monroe Doctrine for western Europe.
But the Atlantic Pact goes much further. It obligates us to go to war if at any time during the next 20 years anyone makes an armed attack on any of the 12 nations. Under the Monroe Doctrine we could change our policy at any time. We could judge whether perhaps one of the countries had given cause for the attack. Only Congress could declare a war in pursuance of the doctrine. Under the new pact the President can take us into war without Congress. But, above all the treaty is a part of a much larger program by which we arm all these nations against Russia…. A joint military program has already been made…. It thus becomes an offensive and defensive military alliance against Russia. I believe our foreign policy should be aimed primarily at security and peace, and I believe such an alliance is more likely to produce war than peace. A third world war would be the greatest tragedy the world has ever suffered. Even if we won the war, we this time would probably suffer tremendous destruction, our economic system would be crippled, and we would lose our liberties and free system just as the Second World War destroyed the free systems of Europe. It might easily destroy civilization on this earth….
