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.

I'll do you even better, I'll give you at least 5 or 6 reasons.

1. Rise of Al Qaeda (Founded in 1988 and funded during the Iraqi war by several nations including Saudi Arabia to bring down Shia government there)

2. U. S intervention is several nations causes outburst of common folk who join Al Qaeda.

3. Al Qaeda becomes involved with other groups who are now starting to form.

4. Syrian war intervention by the U. S, several other allied nations and Russia start several groups, that of which was once apart of Al Qaeda, the Islamic State of Iraq and Syria.

5. Progress in illegal trade, alignment with other groups and production of weapons compensates these groups.

6. The usage of speeches presented by the likes of demagogues as well as force recruitment and evening kidnapping gain more members to the cause.
