Maybe Japan can express regret for the Ukrainian Famine and Russia for the Rape of Nanking. Sort of like humanitarian carbon offset credits.
Any situation where one country is giving the other “apologize” ulitmatums is a problem. Jews now want to blame Poland for the ‘holocaust’. Seems Ukraine is next. Both countries do contain significant right wing elements. Suddenly seems to be attached to the demand that they let the immigrants in or die.
Hmm, well that’d leave out Turkey and the Armenian massacre.
