US intervention in Asia and our support of Britain led to the Japanese attack and Germany's declaration of war.
Yes, US intervention in Asia and support of Britain, so action beyond the official borders of the United States, and therefore not something based on an isolationist policy of a sort similar to that of the Swiss.
Regardless, you mean the US declaration of War on Germany following the sinking of the armed blockade runner Lusitania. An action, the arming of the Lusitania and similar vessels, which violated the assumed agreement between the US and Germany regarding 'non-aligned' shipping. I placed 'non-aligned' in quotes because it was clear to anyone that cared to take an interest at the time that the US was supporting Britain in a material capacity, which is what lead Germany to lift its prohibition on targeting 'non-aligned' shipping.
