What are proper negotiations? Russia will stop shelling civilians if Ukraine cedes them territory? If they're willing to shell maternity wards now do you think they'll think twice about Holodomor 2 to pacify the territory they stole? What about a year from now when they decide they want more of Ukraine? Ukraine should negotiate then and cede more territory? Agree to be a Russian puppet state?
