We tried to stay out of WW2 because we had the same mindset that the Big P has, it cost us 4 times as many dead.
Did our non-interventionist policies cause more casualties in WWII than the War on Terror?
Or was it the fact we were engaged in a two-fronted war across continents, against massive armies possessing weaponry as state of the art as we had at the time; rather than engaging small factions of radicals using guerrilla tactics with improvised devices and substandard surplus armament?
