If Russia retreats from the occupied territories, heaps guilt on itself for the next 80 years and does not start new wars, it won't be vilified 80 years from now.

Also, of course, Germany and WW2 are mentioned constantly in Russia itself even today, while most new wars in the past 40 years have been started by the US or Russia.

What Germany did is many orders of magnitude worse than what Russia does in Ukraine. If you think both are similar, you have no heart, and possibly no brain either!
