Pretty much all the "USA #1" types place Peak America after WW2, not before it. Reasonable historians would agree that it was less of a world power than the European nations before WW1, roughly on-par at the time of the Washington Naval Treaty, and surpassing them at some point between 1930 and 1945. The Great Depression did a lot of damage to individuals but FDR's response to that, and later the war, strengthened the US as a nation.
