I wanted more context than the tweet alone provided about who he was speaking to so I looked at the comments the tweet had below.
I found this:
It was a funny comment but it didn't provide me with more context.
It looks to me like it was the Russian General staff he was talking to. I'm sure there is purpose for him to be doing that otherwise he would have been talking to them. If he intends to lead them then I could see why he was there talking to them.
I think he was there telling them why he is the one who is going to be leading them.
With this and the reports about Wagner turning in their heavy equipment. I see the era of Putin winding down and this war ending. Things are moving in that direction real fast.
