“WWII was a defensive war on our part, fought on two fronts. Good thing we won, and there was no guarantee that we would.”
WWII was a completely offensive war on our part; our defenses consisted of 2 oceans, while we built ships & planes that carried the war to the enemies. Britain in 1940 fought a “defensive war”.
WWII was defensive in the sense that it was brought to us. We did not go looking for it.
