“When totalitarianism overwhelmed Russia and then Germany there was America to roll over first the NAZIs and then the Soviets. ...”
Wrong.
Citing their own moral superiority, Americans struggled mightily to stay out of both big ones of the 20th century - while remaining not too proud to enrich themselves, fostering commerce with both sides.
American dithering during the Cold War was not quite as bad - not quite. But the condescension was still there.
Intervention - earlier in the now-historic timeline, and with greater determination - could have induced the enemies to back down, short of committing the disasters that ultimately did occur.
Who was it that was the deciding factor in WWII. I wasn’t alive then but the history books used to credit the USA with saving Europe’s bacon in WWII. Maybe I remember wrong, maybe it was Andorra. Maybe Mexico was the nation that stormed Omaha Beach. I do remember Reagan with help from Maggie Thatcher and JPII shut down the Soviet economy, or maybe it was the Argentine economy.
