Nail on the head on that one,
The glory and joy to be seen in WW 2 is the victory over murderous regimes who were out for domination by force of there neighbors.
But hey let's look in context, we do that exact same thing now in the West and even by countries of the east now financially.
Nothing the US or any other western power has done since WW2 can ever even begin to compare to the horrors perpetrated by the Nazi's during WW2. Their crimes stand out as singular, calculated and horrific in nature as pointed out earlier. One can scarcely imagine the extermination of the Slav's from the European portion of the USSR had they won, in the name of Lebensraum and the new order.
