Former Danish Prime Minister and current NATO top civilian Anders Fogh Rasmussen explains what the NATO summit in Portgul is all about:
So at a minimum, one thing NATO does is provide something for talented, ambitious politicians from small countries to do. Rasmussen seems to have been a skilled leader of Denmark, and the Nordic center-right parties generally offer a bit of something people all the world over can admire. So maybe when Dominique Strauss-Kahn steps down as head of the IMF we can kick Rasmussen over to an international organization job that has more real authority. His actual background in politics was as a tax/finance guy, not a military guy.
