Not true, but typical of anti-Semites of his time and Holocaust deniers of ours.
In fact, the Nazis systematically murdered nearly two-thirds of Europe's civilian Jews, including:
Overall WWII population losses were approx:
To mention just a few of the worst cases...
Point is: while Japanese losses were significant, many countries, including their ally Germany suffered worse.
quoting Lindberg: "It is alarmingly possible that World War II marks the beginning of our Western civilization’s breakdown..."
PGR88: "WWII just continued what WWI started."
If by that you refer to the loss of European & American colonial empires, then yes, of course, since the country most responsible for their destruction was... that's right, the United States.
Roosevelt's basic deal with Churchill was: OK, we'll pull your bacon out of the fire again, but this time it will also cost Great Britain her empire.
Without American intervention, Germany would have won both world wars, the world's international language would today be German, and most of the world's countries would be either the keepers or subjects of a very few European empires.
We would not like that outcome.
Britain was bankrupt. Lend-Lease had become a euphemism in the latter stages of the war. American aid had kept the UK afloat and in the fight. The Island's people would go through some austere years after the War.
It was clear that after the emergency of the war India would have to be given independence.
The Boers were taking power and taking South Africa out of the British orbit.
Canada had developed a national identity during WWI and WWII. Canada would be a loyal ally but would no longer regard itself as part of an "empire."
The Brits held on a bit longer in Africa, but after the Kenya rebellion it was clear they did not have the resources to hold on there to what for the most part were money losing colonies.
The sun was setting on the British Empire.
