And then, of course, Iraq came and blew it all apart. These upheavals will always take place in the world, and the design and construct of the UN ideally should be such that it can deal with these upheavals, and possibly influence them, and survive and thrive, but it doesn't work out that way, because as an organisation we are so dependent on the same member states.
