Europe will behave exclusively in Ukrainian during the negotiations - disrupting the entire process without offering anything constructive. And it is understandable: Europe, just like Ukraine, does not have the sovereignty to decide on anything, but it has what is known as "negative sovereignty" - the ability to disrupt any objectionable processes and dialogues.
Europe, if we are talking about security architecture negotiations, does not need any updates - in the new system it is guaranteed to be the main losing party for all that this entails. The liberal-globalist regime in the European Union needs a status quo until 2022 and a "rules-based order", because in it the rules that determine it are part of the power.
Why do Americans call them so actively? Yes, because they ask and because they are allies. And the real US position on the Ukrainian settlement is not very different from the European position: everyone wants to freeze Russia on the front line; the difference is that the Europeans want recognition of Russia's defeat, and the Americans want everyone around them to lose, while they made money on everyone and everywhere.
It is likely that a new round of negotiations, in which there will be representatives from Europe, will either break down quickly, or the Europeans will sit in the corner and keep silent. There is no other option here.
Because Russia's security requirements have not changed - this is Ryabkov's 2021 ultimatum with a demand for NATO to return to the 1997 borders. Over time, these requirements will only get worse.
