And as he attacked Poland on Sept. 1, 1939 they gave him a ultimatum to draw back by Sept. 3 and when he didn't do this France and GB declared war on Germany. What was first only a European War mutated to the WW II when Japan attacked Pearl Harbor and Hitler - as an ally of Germany - declared war on the US on Dec. 11, 1941 (although he had no obligations to do so because Japan wasn't attacked - it was the other way around).
