I personally don't believe that. I think war with germany, for the USA, was inevitable. Within 2 months, germany would have had a DoW from them if germany didn't DoW on them first. The USA couold get away with neutrality until they were attacked, but once they were attacked, there was no reason to sit back and let europe stay nazi, perhaps even lose England, or the other alternative was all of europe (except england perhaps) becoming Red. Japan and germany being allies didn't help the USA staying neutral with germany very likely either. The fact that the USA was already helping england to a considerable degree before 12/7/41, put them technically at war with germany anyway, but each side kept ignoring the uboat sinkings and help the british were getting. If the USA had really stayed neutral, then perhaps Hitler wouldn't had declared war. The USA was doing all it could to get involved in the european war and still be looked at by some as neutral. I'm not sure if Hitler wanted to show the japanese friendship by honoring their pact as more of a motivation than the USA getting him angry. That's why I say the USA would had declared war pretty soon, because they were practically at war with germany as it was anyway. Even if Japan didn't attack, germany might had still resorted to a DoW with the USA at some point, simply because they weren't behaving very neutral and if time progressed it would probably only got worse. I guess if Japan didn't attack, maybe Hitler was waiting on reports that the USA had actually put armies in england before he would DoW.
Oh eventually Germany and USA would have been at war, but the discussion is if Germany could have beaten USSR, at time of Pearl Harbor the anger etc of that time was on Japan... which is whay at that time the rage etc of public and congress likely would NOT have been favorable for roosvelt to ask for a DoW vs germany.
It is THAT action by Hitler that Gave roosvelt his ability to do a EUROPE FIRST.
Otherwise it would been a Japan first and only until Germany provoked a DoW like a german sub torping a ship.
The Imminent effect of germanys DoW was to allow US Ships to take full action all way to britain... send massive supplies to britain...start sending troops to Britain and etc..
Without a German DoW I doubt roosvelt could have gotten a DoW vs Germany...not in face of west coast fears, not in face of public anger vs japan, etc.
We can go over this a great deal but we don't really know...
But my view is that without German DoW, roosvelt would have had to concentrate on Japan at least for up to a year...or until Germany acted vs US... that could also have curtailed supplies to USSR, sides britain... given Germany time to concentrate on USSR...
Germany could have brought more troops to USSR since without Britain alone able to re-invade... and likely a reduction in supplies to britain/USSR,
Germany would not have had to keep as many troops in west...
Once USA started sending troops and air fleets to britain, germany HAD to keep troops in West
The fact is germanys DoW did nothing for germany, japan did not aid germany in any way...
it only gave roosvelt his opening to put Japan on back burner... especially as
german subs started full out attks on atlantic and gulf shipping and even some shelling of east coast.
Sorry, but Germanys DoW was shooting self in foot... even if USA had eventually declared on germany, they would have had months of use of extra troops from west areas...
That could have tipped balance vis a vis USSR
And also if roosvelt had to do a japan first and couldn't get a DoW vs germany
USSR if had more setbacks could have made a peace... and Germany then returned efforts vs britain... instead of a D-Day for allies there could been a D-Day for germany and Britain invaded...US troops captured... and USA facing a germany across the ocean...getting smaller by germanys rocketry advances..
Nope, that DoW by hitler was the stupidest thing germany could do and ensured germany was not going beat USSR...
