Although polarization drives some improvements towards democratization and political scientists show that politicians support polarization, divisions have become more one-sided.
Correct answer: George Bush - end of the Cold War
People give various dates for the ending of the Cold War:
The demolition of the Berlin Wall in November, 1989
A peaceful summit meeting between the US and USSR leaders at Malta in December 1989
The reunification of Germany in October, 1990
The dissolving of the Soviet Union in December, 1991.
All of those events occurred during the presidency of George H.W. Bush.
The other pairings noted in the question are misaligned. Haiti had its first democratic elections during the George H.W. Bush presidency. The World Trade Organization was created during the time Pres. Clinton was in office. And the War on Terror began under George W. Bush.
