This extraordinary exchange of Russian state TV is very significant. Most important, in my view, is that is demonstrates that there is enough opposition to the war among the Russian elite that such a discussion could be allowed to occur at all. It is the strongest signal yet that Putin might be deposed, and Russia sue for peace, offering Putin up for prosecution in the International Criminal Court, along with substantial additional concessions, possibly including return of the Donbas, and definitely including a ceasefire (though I do not think they will be willing to give up Crimea). In return, they will ask for all the economic sanctions to be reversed.
