If you mean in WWII then this is what I have got. Germany did not actually declare war on the Americans. When the Japanese bombed Perl Harbour in America the Americans wanted to declare war on the Japanese but the British persuaded the Americans that it was the Germans that started it and so the Americans declared war on the Germans and any other army with them including the Japanese on 11th December 1941. Hope that helps! =)
