hitler was in his mid 20s during world war I, he was not in power in germany
Kaiser Wilhelm II was in power in germany during world war I
US entered wwi april 6 1917, the war was ending by mid november 1918
although there were 4,734,991 servicemembers enlisted during WWI, not all of them went, and the US really did not play a very big part in WWI
get the facts straight
