Final answer:
The rise of terrorism at the start of the 21st century can be attributed to globalization, the presence of transnational terrorist groups, and underlying motivations such as nationalism, ideology, and religion.
Step-by-step explanation:
The rise of terrorism at the start of the 21st century can be attributed to three main factors which can be noted as -
- Globalization: The globalizing world has made it easier for terrorists to reach their targets, spread their message through social media, and inflame people to resort to terrorism.
- Transnational terrorist groups: Terrorist groups like al-Qaeda and ISIS have spread across national boundaries, making it difficult for traditional approaches to foreign policy to effectively counter them.
- Motivations: Terrorism is often motivated by factors such as nationalism, ideology, and religion, as seen in groups like al-Qaeda, ISIS, and nationalist movements.
