I am not making you do anything.
I am just pointing out the reality.
We did not declare war on Germany until they did it first.
If he had done it before the attack you might have a point but he did not.
Since it took a few days it was doubtful it was because of "treaty" and the attack by Japan would have cut any help for the UK off cold.
So he got what he wanted without lifting a finger UNTIL he declared war on us.
Once that happened we were the ones who did not have a choice.
I’ve listened to a lot of radio broadcasts from that time.
The impression I got was that pretty much everybody knew after Pearl Harbor, that war with Germany was inevitable.
