There are both things in international law: the principle of territorial integrity and right to self-determination.

If we speak calmly, in a businesslike fashion, let me draw your attention to the fact that Russia supplies arms to the legitimate government of Syria in full compliance with the norms of international law. We are not breaching any rules and norms.

In line with international law, only the U.N. Security Council could sanction the use of force against a sovereign state. Any other pretext or method which might be used to justify the use of force against an independent sovereign state are inadmissible and can only be interpreted as an aggression.

International law says people fighting for self-determination can use force in order to achieve their independence.

Governments are mandated by international law to protect people from genocide.

Pre-emptive war might fall within the framework of international law.
