Answer: Before the attack on the Perl Harbour the attitude of America was neutral.
Explanation: The American public, as well as the official policy of US diplomacy and government, was neutral in the war in Europe. In the American public, Germany was labelled as the main protagonist of the war and the main aggressor in Europe, and generally there was not much concern about the potential entry of the US into the war. There were longstanding tensions with Japan, but no one predicted that such an attack could have happened, as it was at Perl Harbour.
