" Did not realise his mistake...saw his arse eventually in Stalingrad, Moscow and Leningrad."
When it comes to the invasion of Russia, Operation Barbarossa, the German generals are just as much to blame for its failure as Hitler, Operation Barbarossa was the baby of both Hitler and his generals and it was a bad plan.
"Bonaparte did the same thing to his peril."
There is some similarities but there is also a number of differences between the two invasions.
"Russia has played a trump card in history and we owe them a lot of
respect...I just wonder what would have happened without them."
In respect to WW2 its a difficult question to answer. If there was no Eastern Front, the British Empire and American's would have been facing millions more troops, thousands more tanks, and artillery pieces, the full strength of the Luftwaffe not about a third of it. North African and the places like Malta would have fallen to the Axis and it difficult to see a successful the Allies successfully invading Europe unless both America and Britain substantially increased the men and resources they could throw at it and where willing to sacrifice millions of men. Conversely Germany would still not be in position to invade Great Britain, let alone even remotely threaten the Americans and even if the Russian's had continue to supply them oil they would be 1943 be really struggling with an oil shortage.
Had Russia fallen and Germany got its oil supply by 1942, they would have sustained substantial casualties but their oil shortage is solved putting the Germans in a better position to fight off an Allied invasion of Europe. Could possibly give them more time to get the ME 262 jet fighting into production and ward off the Allied bomber offensive. Still at this point I can't see the German's having the means to invade the UK and the American's will get nukes first.
Successful invasion of Russia and the Germans warding off an Allied invasion of Europe possibly means Germany could remain masters of continental Europe and Western Russia, and millions more dying due to the holocaust. A bad outcome for the world. The Germans may have just ended up getting nuked either.
"Then war between Germany and Russia relates to a difference in
personalities of the leaders involved - both were so-called socialists
with the besotted idea to rule the world, Millions of innocent people
died because of that insanity, "
Neither Stalin or Hitler liked each other but to say the war was due to a difference in personalities is none sense. Hitler was really a socialist in name only. He did want Germany to dominate the world but didn't expect to live long enough to see it. Stalin wanted to see Communism exported round the world and the USSR become the defacto leader of the communist states but never had any plans to invade and occupy continental Europe like Hitler did.
"Attacks in Russia has always ended in disasters for the attackers and
one would have learned from history and avoid it like a plague - but
the current politicians are more interested in the Cancel Culture than
to learn from history what should be avoided at all costs"
Except when they don't. For example Germany beating Russia in WWI. Or Russia losing a war to Poland in between the two world wars.
Why on earth are you going on about cancel culture, what on earth has that to do with WWII and are you suggesting their is politicians out their currently considering an invasion of Russia?
"Russian resilience coupled with the catalystic effect of frozen winters
is what won both wars especially with Napoleon and not so much with
Germany as it Russian soldiers ability and heart and defeated the best
armies in the world... Napoleon was the best Field Marshal, Hilter was a
fool but both were defeated by the 2 mentioned factors."
Yes to Russian resilience, no to the cold. In the case of Napoleon, his army sustained most of its losses before the Russia winter had kicked in. Likewise German causalities and its logistical system collapsing where the decisive factors in 1941 and this had already happened before the Russia winter kicked in. In both cases the Russian winter served to make a disastrous situation even worse but the disaster had already occured. Napoleon was not doubt a great military commander, one if not the best of all time, but historians where not so impressed with his leadership in Russia was not considered on the level of his other campaigns. Hitler was no where near Napoleons level, but I wouldn't call him a fool, he was actually above average intelligence. He did make a lot of mistakes but so did his generals.
