I don't think the alliance works with sticks as well as it does with carrots, and I don't think anyone would go as far as talking about expulsion or anything like that.
In fact, the Wales commitment was made by all the alliance nations. It's not been imposed by anybody. They all said, “This is what we're going to do”, and if one or more alliance members are now saying, “All we're asking is for you to do this”, there is massive moral pressure to do it. I don't believe for one moment that anybody would say, “You can't play if you don't contribute”. But, yes, it will be increasingly embarrassing for those nations that are not moving in the right direction and don't have a demonstrable plan for getting there. That's the way the alliance will work. It won't work in terms of imposing sanctions or this sort of stuff.
