If you like, Mr. Chair, I'll start and then pass it to General King.
The funding of security forces, as you point out, is enormously expensive, and there's no question that the Afghan government is going to need the support of the international community for a long time to come. I don't have the numbers, but there's also no question that it is cheaper to assist the Afghans to do their own security than to keep deployed forces there. Here you've talked about the U.S. contribution to this effort, and to keep U.S. troops in Afghanistan doing that business, for example, it costs a lot more.
But in many other post-conflict situations around the world, we've seen this need for sustained engagement and for developing the security forces, because the worst thing you can do is to kind of stand them up and then leave them and not fund them. So issues of pension and making sure that you're bringing in recruits and they're getting a reasonable wage, and that you're dealing with issues of corruption and things like attrition, are absolutely essential. Those are the sorts of discussions that, again, you may want to raise with our DFAIT colleagues, I think, in more detail. But those are the discussions, let's say, in the Friends of Afghanistan and that go on in the UN context and with the Afghans themselves as they stand up their economy. It's going to be a long-term process.
I don't know if you have anything to add, General.
