That's a re-write of history. The Roosevelt administration Congress has approved the Lend-Lease act which meant active involvement in Europe with armaments, active naval combat in the North Atlantic, and ground troops in Iceland. The US had started building a 'two ocean' Navy almost two years before Pearl Harbor. Pearl Harbor was a final gift to the Roosevelt administration's multi-year program of full mobilization. This program of support and mobilization absolutely was in response to events in Europe and a desire to see the UK in particular not fall. Note that when the US did enter the war, the Pacific was designated the secondary theater of operations.
