I'm not entirely sure that is correct. Japan attacked Pearl Harbor; US declared war on Japan; within days, US declared war on Italy and Germany. IIRC, the date was December 17th. I also recall--but I could be wrong on this point, I'm no historian--that, up to that point, Japan was the only Axis power to have declared war on the US.
I remember this point being debated on the forum when the US began "Operation Kicksomeass" in Iraq...all the liberals of the world were moaning about "How could the US behave aggresively toward a country who had not openly declared war on the US?"
Anyone know the WWII dates for sure?
Germany and Italy declared war on the USA on December 11, 1941.
