Russia only condition is not attack Russian territory with Western arms untill it officially annex Ukraine become part of Russia.Because they can't deter Turkey (or US) for sending arms to Ukraine. Russia warns United States against sending more arms but HIMARS still being sent lol. US or Turkey do not care about those useless weak warnings because RU can't do shit. Escalating is done by the superior or equal force not the inferior.
the rest is control experiment to train and test combat in realistic conditions.
