Andreas Umland, "Selbst wenn sie einen Kompromiss wollten, wäre er nicht zu erreichen – die verfassungsrechtliche Sackgasse des russisch-ukrainischen Konflikts" https://www.nzz.ch/meinung/die-verfassungsrechtliche-sackgasse-des-ukraine-krieges-ld.1723682

The main reason why demands for negotiations between #Ukraine and #Russia are so utter pointless:

Since the amendment of the Russian constitution in 2014 (after the annexation of Crimea and its incorporation into Russian territory) and the amendment of the Russian constitution in 2022 (after annexation of the four Ukrainian oblasts and their incorporation into Russian territory), any Russian president or his negotiator would break the Russian constitution and commit high treason if he were to negotiate over these territories. At the same time, every Ukrainian president or his negotiator would break the Ukrainian constitution and commit high treason if he were to negotiate over these territories. Both presidents are obliged to defend and preserve their respective constitution.

That is: Russia as well as Ukraine, at the price of breaking their constitutions, cannot negotiate over these territories. Thus, only the war can decide who will have to amend his constitution.

So much contra the cheap Left who claims a) that negotiations are possible if people only want to; and b) that in reality it's the USA that is prolonging this war. Learn something!
