In the war among states...
In the war among states, only force reigns and each one of the parties seeks to overcome the enemy through, all means and might. In this cause, religions, moral schools, philosophers and lawyers have endeavored throughout history to limit non-humanitarian acts in war by formulating the laws of war.
Some people believe that there is no need for formulating the laws of war as the Suppression of the Act of Aggression for limiting or forbidding the acts which are tinged with crime, believing that the setting of such rules implicitly lends legality to war.
However, the fact is that the illegality of resorting to war does not at all obviate the need for the laws of war and humanitarian rules, for such laws aim to reduce the ill consequences of the inability of international community in forbidding war.
After fifty years, the United Nations has failed in the total elimination of this bitter truth despite the prohibition of resorting to force in international relations and has been incapable of determining the aggressor and has failed to do its duty in forbidding or stopping aggression although it has achieved great success in organizing the laws of war especially in approving the humanitarian acts.
Besides, it played an important role in organizing the Geneva Conference, which led to the 1977 protocols known as the Four Geneva Conventions (1949). In addition, the Convention of the United Nations in 1981, which banned the use of lethal weapons, was one of the innovative acts of the United Nations. Recently, the Commission on International Law studied the crimes against peace and security perpetrated in some areas such as the former Yugoslavia and had the court and the laws of court approved.
Basically, the laws of war seek to enact three limitations for armed operations as follows: A) Limiting the war zone B) Limiting the use of weapons C) Limiting the operations to combatants and immunity of the civilians.
