It's about the sustainability, exactly.
I would just revert almost to point one, which I always remind myself. Unlike in many other places where we've tried reform, this is our helping Ukraine implement the reform that it has said it wants. Its president, its Rada, has said that their aspiration is Euro-Atlantic standards and principles, that it is NATO interoperability. I'm not telling some senior general who's served for goodness knows how long, “You have to change. Your government has said...and that's why your folks got out and did Euromaidan.” It's not my coming in, it's not a bunch of western do-gooders. It is intrinsically Ukrainian, and I think that's a really important point of departure, for me, anyway.
