I wonder if I can stop you there. Thank you very much for that; it's helpful.
My second theme has not been broached this afternoon, but obviously people are thinking about it. What is the state of global nuclear disarmament efforts, before and now, through this crisis? Do you have any thoughts on the status quo? Is it shifting? Could it shift? Is it really more firmly entrenched than ever?
If I can get 30 seconds from you, and also from the general on that, that would be helpful.
