In the 1990s, the international community was heavily criticised for failing to intervene in the Srebrenica massacre and the Rwandan genocide. This influenced NATO’s bombing of Kosovo in 1999, which was conducted to stop the ethnic cleansing of Albanian Muslim Kosovars by Serbian militias. Although the military intervention by NATO was widely deemed successful in preventing ethnic cleansing, an independent commission found it to be “illegal but legitimate”. In a move to codify legal humanitarian interventions, in 2005 the UN adopted The Responsibility to Protect (R2P) doctrine. It states that each individual state has a responsibility to protect its population from genocide, war crimes, ethnic cleansing, and crimes against humanity. The UN is prepared to take collective action, in a timely and decisive manner, through the Security Council should peaceful means be inadequate and national authorities fail to protect their populations. After NATO intervention in Libya, which was not authorised by the Security Council, some scholars and diplomats argue that R2P has lost its credibility in the eyes of the international community and is seen by some as a dated norm. Since 2012, R2P was not invoked in several instances of crimes against civilians, such as in Syria, Yemen and Myanmar.
