Generate text that refutes this claim: The UN has been at the forefront of promoting respect for international law and human rights.  When the United Nations was founded in 1945, the idea of “international law”, in so far as it had any meaning, was little more than the customary behaviour of states towards each other. Over the succeeding 60 years, the UN and its various offices and organs have taken a lead role in codifying and promoting the concept of international law and the protection of human rights. For example, the crime of genocide was first enshrined in international law in the 1948 Convention on the Prevention and Punishment of the Crime of Genocide.

global house believes united nations has failed
The UN has been only one among many organisations which have shaped the modern doctrine of international law. More influential in developing our contemporary understanding of human rights, arguably, was the worldwide horror at the Holocaust, Nuremberg war crimes trials, and the determination of the West to hold developing nations and Communist states to the same standards that they [supposedly] adhere to. When activists in undemocratic regimes fight for better civil rights, it is seldom the UN they cite as their model.  It is fair to ascribe the United Nations its due share of credit for this emerging consensus, then, but it has been remarkably bad at actually encouraging, let alone enforcing, the rules it has helped to create.
