This group is a great idea. With the UN's dysfunctional inability to act on anything, it would be ideal to have a group that is more responsive to the world's problems. NATO would be an option, but this would be the developed world domintating the rest. With nations from all parts of the world, the L20 is not just one group of countries (the west or north) dominating the rest. It's the leading nations of the world together taking action.
