I agree that we had a good reason to enter WW2, and all and all it really helped out our economy while doing some good for the world. However I know that from hindsight, if i had been alive at the time i would have been very hesitant to enter the war. Especially knowing how WW1 went for us, thousands of Americans dead in a European war for no gain whatsoever. I'd be a fool to repeat that mistake, especially during the great depression. And that's how most Americans thought at that time, if the Axis had never declared war on us its doubtful we would have entered the war at all.
