most significant date in WWII
This came up in conversation yesterday and I did have a definitive answer–not that there is one, necessarily.
September 1, 1939 or December 7, 1941
After a lot of lead up, September 1, 1939 directly caused a war, one in which many countries declared war on others.
December 7, 1941, on the other hand, only brought one country into the war, but it probably changed the outcome.
I think August 6, 1945 is significant, but, I think, more for the Cold War than the WWII.
And, honestly, you’re just being a contrarian if you say July 7, 1937.
