While the system of international law is improving enormously and certain legal provisions are becoming an integral part of jus cogens norms, this body of law must be studied together with other systems which have basically been effective in its development. The principles of the rule of law must be evaluated collectively rather than selectively. In fact, most Islamic nations have ratified the ICC Statute. They have thereby contributed to the establishment of the pillars of morality, equality, peace and justice. At the same time, those pillars may be strengthened by means of an accurate interpretation of the principles of international criminal laws by all parties. The objective of these comparative philosophies is to examine their core principles, similarities and differences. The intention is to indicate that the variation in theories may not obstruct the legal implementation of international criminal law if their dimensions are judged objectively and with the noblest of motives towards mankind.
