Three events that contributed to the rise of terrorism at the start of the twenty first century?

There are many events that contributed to the rise of terrorism in the twenty first century. Three examples are:

The Soviet-Afghan War: The Soviet-Afghan War lasted from 1979 to 1989. The war was extremely destructive, and the institutions of Afghanistan were severely weakened. The rise of the Taliban: Due to the destruction of previous conflict, the Taliban was able to capitalize on the chaos and gained support in Afghanistan. The terrorist group shared some of the goals of other terrorist organizations, such as al-Qaeda.American interventions in Afghanistan and Iraq: In an effort to address the terrorist threats, the United States invaded these countries. This only caused more hate towards the West, more casualties and more destruction, making it even more difficult to restore peace and order in these territories.
