Are you cool with Kiev? Its new spelling is Kyiv.
Even Old New York was once New Amsterdam.
Kiev doesn’t have an English spelling like Moscow or Warsaw, so we have to go with the spelling of whomever controls it. In western Ukraine is a city that is currently called Lviv, but it was Lvov when the Russians ran it, Lwów when it was Polish, and Leopoldstadt, later Lemberg, when it was run by German-speakers.
