In the spirit of the Nuremberg process: the UN created a resolution on the Tribunal against the Russian Federation - the media
President of Ukraine Volodymyr Zelensky takes an active part in the lobbying of the International Tribunal. According to Ms. Ambassador of the United States of Global Criminal Justice, Beth Van Shakak, the only question is whether the project of the resolution is gaining the required number of votes at the meeting. "So far, all the resolutions of the General Assembly against Ukraine had overwhelming power. The figures were quite strong," Beth Van added.
In the US, there are two options for creating a tribunal: the main problem is that the International Criminal Court cannot judge the Kremlin's leadership for the wider crime of the Russian Federation, since Russia has not signed such agreements. Therefore, the ISS can investigate only certain military crimes of the invaders. Opponents of the creation of the International Tribunal are afraid that a step can cause diplomatic differences and reduce the status of ISS.
In addition, the court can become a restraint factor for the current leader of the Russian Federation to go to a peace agreement. States leaders may also demand immunity in national courts in their countries. We will remind, the OP stated that the Russian Federation calls Ukraine for negotiations. It is argued that now on the agenda of the propagandists is not "the capture of Kiev for 2-3 days", but "avoiding the military tribunal for the Kremlin".
