Abstract
This article will consider the primary legal issues under international law on the use of force presented by Hybrid warfare. The legal terminology with regards to warfare has developed separately under laws on the use of force and the laws of armed conflict. Under the UN Charter, for example States have the obligation not to use force in their international relations and to settle any dispute peacefully. It constitutes a general prohibition on the threat or use of force and concludes that all Members shall refrain in their international relations from the threat or use of force against the territorial integrity or political independence of any state, or any other manner inconsistent with the Purposes of the United Nations. Nevertheless, the UN Charter provides exceptions to the use of force through self-defence and the authorization of the Security Council to maintain or restore international peace and security. Mainly concerns are raised about the abuse of such thresholds by adversaries for their own tactical and strategic advantage.
