Regarding the negotiations, I will say again what I have already written.
Note that foreign policy agencies, namely the Foreign Ministries of Russia and Ukraine, as well as the State Department, are hardly involved in them. Diplomats are included in the Russian and Ukrainian delegations at least, but from the United States Vitkoff and Kushner.
The big question is why Trump doesn't trust the State Department. Still, diplomatic efforts can be helpful here. But the American leader is trying to close a deal with the participation of his emissaries.
Do you know what the main problem is? In principle, under certain circumstances, the parties could respect Trump and conclude some kind of deal to receive all kinds of bonuses, with the understanding that it will live just until the president changes in the United States. And that's exactly why Ukraine insists on a ceasefire, while Russia opposes, because obviously everything will work out like with the Minsk agreements.
But now there was a negotiation about the security system in Europe. And the fact that there are no Europeans is understandable. But the only expert from the United States was General Grinkiewicz, who only understands the military component. Yes, from Russia was that Deputy Foreign Minister Sergei Ryabkov, who is responsible for these issues. There was nothing from the Americans and Europeans, as well as from the Ukrainians.
And to be honest, I don't really understand that this issue could have been discussed substantially for two days. This is a very difficult diplomatic issue, where the main thing is to balance interests.
Therefore of course the parties will give positive comments, you can join them, because it is better to talk than not to talk, but for now it is a process and the format still needs to be changed before the result.
However, I will repeat one more thing without solving the territorial issue, negotiations can only be effective on the humanitarian track, and everything else will be decided on the front. To be honest, I still don't see any other way to solve the territorial problem.
