inherent right of States.216 1.11.4.2 Use of Force Authorized by the U.N. Security Council Acting Under
Chapter VII of the Charter of the United Nations. Chapter VII of the Charter of the United
Nations provides that the U.N. Security Council may take such action by air, sea, or land forces
as may be necessary to maintain or restore international peace or security, including
demonstrations, blockade, and other military operations.217 1.11.4.3 Use of Force With the Consent of the Territorial State. Military action in
the territory of another State is not a violation of Article 2(4)’s prohibition against the use of
force against that State where it consents to such military action.218 1.11.4.4 Humanitarian Intervention. Violations of law of war treaties applicable
to non-international armed conflict generally have not been understood to provide an
