I was just reading a piece about Canadian frustrations with the UN,
UN failing victims of war, Canada says, (caveat lector, the National Post is known to be right leaning). Here's some of that:
Allan Rock, Canada's ambassador to the UN, said the council shies away from many "sensitive and politically challenging" problems, but must become "more creative" if it hopes to fulfill its December, 2003, pledge to entrench civilian protection as a "central commitment."
His blunt message reflects Ottawa's frustration with the UN, which has long been a central conduit for expressing Canadian foreign policy but has been slow to adopt Canadian-endorsed ideas for protecting civilians caught up in wars.
The Security Council, the UN's foremost body charged with ensuring international peace and security, invited non-member states such as Canada to speak in yesterday's open debate on the topic.
"Today's debate affords the first opportunity to measure the council's actions against pledge," Mr. Rock said. "We can only conclude that a significant gap remains between Council commitments and concrete action."
Okay, the UN is an instrument of foreign policy. (So is the state from a certain point of view, but that's another matter.) Nevertheless, there seem to be many, many cases where states share similar interests. After all, what national interest does Canada have in protecting civilians caught up in wars? I don't recall Canada having been militarily attacked in my lifetime. And yet the fact remains that Canada has a general and abiding interest in preventing international conflicts and promoting peace. Every member state has that in their interests, more or less. The UN remains the preeminent international body for discussing and promoting shared policy interests in the peaceful coexistence of nations.
It's possible that the crisis moment you are noticing reflects difficulty coping with an actual increase in violent conflicts, rather than a complete breakdown of the institution. I agree with you that reforms are needed and that there is room for criticism of UN leadership, and also the way member states have abused or manipulated the UN. That doesn't ammount to an institutional crisis, utter aesthenia or zero credibility.
