Human Rights laws are defined as a set of rules that sovereign governments should be subject to and form international legal constraints to prevent them from abusing the rights of their citizens. Human Rights laws are a relatively new phenomenon, although the idea that human beings have certain inalienable rights is not new (Word Politic in A New Era p449). It is clear that human rights go hand in hand with international law. The UN and international law are liberal as they wanted to establish a peaceful world. “With the end of the cold war, countries have been more willing to consider enforcing human rights guarantees with multilateral intervention, at least in principle.” (Word Politic in A New Era p452). It is hard to execute human rights during the cold war, unlike realism that has aggression and warfare.
