Schröder is totally right. It's only a joke of history that the Krim was Ucranian territory. A Soviet Czar donated the Krim to the Ucraine on totally strange reasons. Comparable: When Donald Trump personally donates Manhattan to Puerto Rico and Puerto Rico will leave the USA - belongs Manhattan in this case to the USA or to Puerto Rico, when the same people live in Manhattan as before had lived there?
Sure a crazy problem - but as crazy is the problem "Krim". For sure should the "Ruthens" in Russia (Russians) and the "Ruthens" in the Ukraine (Ucrainians) stop to murder each other. What an idiotic nonsense under brothers and sisters. Such an unimportant problem should easily be solvable by speaking with each other.
