I would point out that almost all of our strategic arms controls, and everything like that, are basically focused on Russia. We have the entry of China in the game in a somewhat credible manner. Most of our architectural thinking about these risks is essentially just looking at Russia. If anything, there needs to be a reflection about how we can bring China into this, and how we can have more transparency.
I would note, in terms of what's going on in Ukraine, that we are seeing the use of missiles there now. We're seeing that there are issues with them, and this is raising the risks.
I'll pass it to my colleague.
