Poland has declared a new name to use for the currently Russian city of Kaliningrad. Poland's choice choice of name, Królewiec, was the Polish name for that city during the short period, 1454 to 1457, that the city was under Polish control. Aside from those few years, the city's name was Königsberg for 7 centuries.

It seems to me that Russia and Poland are both being fools about this.

Russia is a place of horrible tyranny and repression. Poland is a place of diminished human rights and imposed Christian restrictions. Those issues are more important than the name of Kaliningrad.
