maybe when we throw in Germany, Japan and Italy at war with the US too, the hole thing becomes more balanced
This is how it would go.
Remember the Tizard mission? So no early RADAR for the USN owkay. That's important.
Also, the early USN torpedoes really were terrible.
But... what is Britain supposed to do without all that overseas resource not coming in from the USA?
Can we assume they get resources from the continent? Sweden, perhaps & the USSR?
So...
The RN wins pretty much every engagement, quite convincingly, despite severe fuel shortages etc. etc. up until about mid 1943 when a serious number of Essex class CV, Baltimores, Gatos, etc. etc. start to appear.
Then, with large numbers of modern naval aircraft, the RN would get hammered.
Not to mention the US ability to build as many destroyers as the UK can build tanks.
And 100 CVEs
It just starts to get silly.
Yes.
Next question?
Sure, the US Army and Airforce were tiny compared to the major powers in 1940; the major powers were fighting a war, while the US wasn't. That said, they mobilized quickly and performed decently once they did so, certainly compared to the British early war experience (compare the prolonged defense of the Philippines with the British in Malaysia, for an example). This has nothing to do with any supposed mythic US military prowess (which I agree is overrated), and everything to do with the fact that the US is a giant country, separated by giant oceans from any enemies. Canada is not an adequate base to launch an invasion without serious build-up, which would cause the US to mobilize. And once the US has mobilized, it's not even a contest; the US industrial base was basically equal to the rest of the world combined, much less just the British Empire.But the truth is different
until 1940 USA Army and Airforce were pathetic compared to rest of major powers
and they navy wasnt anything special, compared to japan or UK it was behind on technology.

And the USN was certainly not behind the UK in technology; it was lacking in some things, but ahead in others (e.g. carrier aircraft and carrier doctrine, which explains how the UK managed to lose a carrier in a surface engagement in 1940).
So in the air (in a carrier battle), the US will generally have a substantial numerical advantage. Add to this that the US aircraft were better than the British (for its carrier bombers, Britain mostly used the Fairey Swordfish until 1943 or so. Its a bi-plane..). Their fighters were also second rate, like the Fairey Fulmar (They did make a naval version of the Spitfire, the Seafire, but it was not a success as its airframe simply could not handle the stress of carrier landings).

3. Land atack from Canada (remeber side that atacks is always better off)
Was american ships even suited for the atlantic, I have heard that they had stability problems which would be a hugh disadvantage. I have also heard that the british considered the american ships to be underarmored. British had as good fire control as the americans and have better anti aircraft designs (Pompom was better then the americans anti aircrafts designs) if you discount the foreign designs, at least US would not have kerrison predictors if hostility started in the 30s.
British would probably be able to hold of the americans in the atlantic.
Now conversely, could the Americans attack Britain? Assuming the same rules apply and Weimar still rules Germany etc?
and they navy wasnt anything special, compared to japan or UK it was behind on technology.
Stability dosn't seem to have been that much of a problem for USN. Brown (in Nelson to Vanguard) points out that the DDs lost in the Pacific Typhoon were still good compared to older British stuff. He also seems to value Fletchers highly in terms of wetness. I'm also reminded of some of the incredible feats of survivability USN pulled off. Like supposedly top heavy Cleveland being towed safetly home after extreme damage and flooding.
