The Russian government may not say anything, and that's kind of good news for a change.
If it's true that the US President's National Security Advisor and key advisers to Vladimir Putin are talking about how to avoid a nuclear escalation in Ukraine, it may well help the cause if little public fuss is made about it.
So far, only Russia has escalated verbally.
And, unfortunately, there is no guarantee that even in the event of further defeats on the battlefields in invaded Ukraine, at least the nuclear sanity of the Russian leadership will remain intact.
Kyiv decides
But that is precisely why it is good and right to stay in touch with Moscow on this issue.
If you hear what is being trumpeted from President Putin's environment, you get an impression of what the Kremlin perceives as "reality" in the world.
US-Russian talks about nuclear de-escalation are also in Ukraine's interest.
Fortunately, the federal government has made it clear once again that the government in Kyiv will decide on the basis of its own sovereignty whether it makes sense to enter into general negotiations with Russia about withdrawing the invading troops.
Since Moscow is not making any such moves, such talks would probably be pointless at the moment.
