In 1979 there was a big shift in the way the Muslim world dealt with the rest of the world. In that year, Egypt made peace with Israel, Iran became an Islamic state after a revolution, and there was an invasion of Afghanistan by the Soviet Union. A lot of things changed in that year. By 2001 the Soviet Union was gone, Jordan had also made peace with Israel, and on September 11, 2001 there were major attacks on the U.S. - which most people believe were made to drive the United States out of the Muslim world, especially Saudi Arabia. In many ways the events of 1979 led to the events of 2001.
