The end of the Cold War and the beginning of the era of sustained economic expansion coincided during the 1990s. On January 1, 1994, Canada, Mexico and the United States signed the North American Free Trade Agreement, creating the world's largest free trade area. In 2000, Vicente Fox became the first non-PRI candidate to win the Mexican presidency in over 70 years. The optimism of the 1990s was shattered by the &lt;a href="9/11"&gt;9/11&lt;/a&gt; attacks of 2001 on the United States, which prompted military intervention in Afghanistan, which also involved Canada. Canada did not support the United States' later move to invade Iraq, however.
