Bush strode to a podium in Mainz, West Germany to explain his vision of what Europe could be like if the Cold War ever ended. “The passion for freedom cannot be denied forever,” President Bush told West German Chancellor Helmut Kohl and others who gathered for his speech. “The world has waited long enough. The time is right. Let Europe be whole and free.”
