Answer :
The three factors that led to the rise of terrorism at the start of the twenty-first century are:
1. The Palestine-Israel conflict: The long-standing conflict between Israelis and Palestinians has fueled tensions and provided a narrative for extremist groups to exploit for recruitment and support.
2. Political instability in the Middle East: The instability in countries like Iraq, Syria, and Afghanistan created power vacuums that allowed terrorist organizations such as ISIS to emerge and thrive.
3. Tensions between Sunni and Shia Muslims: The historical religious divide between Sunni and Shia Muslims has been manipulated by terrorist groups to incite violence and further their agendas.
