People / Governments have tried to reason / be reasonable with Putin (and let's not kid ourselves, Putin is just the old Nomenklatura in a nicer suit and with better PR), and he doesn't play that game - it's difficult to be reasonable with an unreasonable opponent (as I'm sure you've found on this forum

).
But who, in over 3 generations, has tried to invade Mother Russia?
Anyhoo, have a great Christmas, and best wishes to you and yours.
Счастливого Рождества
