That's a rather Euro-centric view, Walter. I'm sure the Ethiopians and the Chinese might have something to say about that.
It also started for Australia, Canada, and I would guess a number of other Commonwealth countries on that day.
Given that the Chinese had already been viciously and horrendously attacked by an Axis power, (though I am not sure that Japan was formally an Axis power at that point) and a number of countries nowhere near Europe decided that Hitler was worth fighting right there and then, I think your comment re Eurocentrism is quite misplaced.
My mother and uncle enlisted almost immediately, and my uncle was flying in the RAF, as were many Australians and Canadians, at the very least, as soon as they were trained, and until the bitter end.
The US was very late to the struggle...but many countries NOT anywhere near Europe were not.
My uncle killed himself as a result of PTSD he suffered because, after D Day, when he knew he was killing Allied troops in his bombing runs because Intelligence could not keep up with the frontline: and pondered what could have been so awful that he did not experience similar horror with this extraordinarily gentle and sensitive man's murder of German civilians during Bomber Harris's fearful attacks upon German civilians.
I find myself in tears at the anniversary, as I think of the horror and slaughter experienced by so many millions upon millions of people.
I grew up with the traumatised folk who fought from 1939 on.....I heard the stories of the terrible atrocities visited upon Australian, British and Asian captives and conquered victimsof the Japanese from those who experienced them and, against all the odds, lived....though forever with guilt.
I heard my mum describe the deaths of her dear friends in England and numerous other countries, and saw the photos of these men posed against their Spitfires, snow in Bethlehem, and other backgrounds for their untimely deaths.
I so do not generally do national pride and such crap...and I am aware of the awfulness of theWW I treaty of Versailles and all the other **** that led to this.....and all the other awfulnesses everywhere......
But I find your nit-picking quite untoward and distressingly inaccurate and USA-centric.
I think today of the millions who died, and the millions traumatised beyond belief.
And wish them peace.
