If we have proof of nuclear and biological weapons, why dont we show that proof to the world as President Kennedy did 40 years ago when he sent Adlai Stevenson to the United Nations to show the world U.S. photographs of offensive missiles in Cuba, Daschle said at the National Press Club news conference. By revealing the photos, Kennedy let the Soviets know the exact limits of our photo recon capability. This was a major deal at the time, since this capability was top secret in the extreme.
Didn't it cost us a U-2 at one point? I believe it did.
