I support what Richard has said.
The other thing to keep in mind is that our intent from the export control community, and it is a fairly wide multilateral community that co-operates on the establishment of effective export control regimes, is to broaden that to as many countries as possible. The countries that are at risk of instability or are currently experiencing conflict need effective export control regimes, so while the intent of the treaty is universalization with every country in the world being part of it, there are incremental steps along the way that don't diminish the treaty's effectiveness.
