Boys, how else are you going to stop the war? Real answers.
It would be nice if Russia could just get what they deserve, but the whole worlds military are not going to get involved, so it isn't realistic. Ukraine should absolutely be involved in the talks, but Russia are the ones with the ball here. How else are you going to stop this? It isn't about appeasement, concessions, or punishment. It is about putting an end to the killing as soon as possible with the most diplomatic means necessary.
It will pause the killing. It'll be a temporary ceasefire in all but name really - like the Budapest Memorandum and Minsk Agreements, amongst many other treaties or agreements they have violated.
