Even without the word “terrorism,” several Charter principles are relevant:
Use of force (Article 2(4))
- States must not use force against other states
- This includes supporting armed groups that carry out attacks
Self-defense (Article 51)
- A country can respond to an “armed attack”
- This has been interpreted (especially after 9/11) to include:
- attacks by non-state actors (terrorist groups)
Terrorism is mainly dealt with through UN Security Council resolutions and later agreements.
Key example:
After 9/11 — Resolution 1373 (2001)
The United Nations Security Council required all countries to:
- Criminalize terrorism
- Freeze terrorist assets
- Deny safe haven
- Share intelligence
This effectively created a global legal framework against terrorism.
