Because as I understand it, the US was largely aloof until Germany started pursuing atomic weapons and even then the Manhattan Project was done very secretively. So until Hitler started incarcerating millions of people and threatened all out war on Europe, the US wasn't really bothered all that much. So naturally Germany hits the headlines for the final 2 years of the war, and then Japan for a year because Pearl Harbour and Hiroshima/Nagasaki bombings.
