The Doctrine of Responsibility to Protect (R2P): Promote Human Rights or Just War Theory

Lack of popularity for some governments and the crisis which occurred in the decades after the establishment of the United Nations in the world, made the then Secretary General for the United Nations to raise questions to the international community in General Assembly in 1999, including: in the situation such as Kosovo and Rwanda, if the governments are reluctant or are not able to protect their population against the humanitarian crisis, the rest of the world should wait for the authorization of the Security Council, do nothing and just look at the crimes against humanity? On the other side, will the intervention without the authorization of Security Council weaken the fragile system of post second world war? And will not provide the pretext for future intervention in internal affairs of the other countries?
The 2005 Summit reaffirmed this matter. In that meeting, the States reached the consensus that, the situations in which the governments are reluctant or are not able to protect their population against genocide, war crimes, ethnic cleansing and crimes against humanity; the international community has the responsibility to protect those affected populations according to chapter 6 and 7 of the Charter of the United Nations.
By review the theories of the just war, simply can figure out that the responsibility to protect doctrine is the same with slight changes. In the report of the ICISS, the legitimacy of military reaction is possible after meeting the 5 condition borrowed from just war theories, but the legality of it needs the authorization of the Security Council according to the United Nations Charter as the sole authority to issue the authorization for military reaction.
