In 1960, Americans and Soviets stopped trying to end the arms race after this famous event:?

D - the infamous U2 incident.May 1960.On the advice of the CIA,President Eisenhower lied about U2 aircraft flying over the Soviet Union.Kruschev caught him in the lie by publicly displaying the wreckage of the plane and its live captured pilot.I was a small boy at the time and recall how shocked people were that Eisenhower lied.In those days a president telling a lie almost never happened.
