Totally false, as the British Empire is not in the dire economic straits the Nazis are in.he's pointing out that to defeat Germany, Britain will have to:
invade the continent with enough men to defeat the Nazi armies.
This will take a huge, mega effort that Britain has no means of doing without America footing the bill. It is probably impossible even with American financing
Germany doesn't need to invade Britain. By the time something like Sealion becomes possible, it has long since become unnecessary: Britain will collapse from the lack of imports
Britain just needs to outlast the crumbling façade of a state that is the Nazi Empire.
For people that think Britain couldnt win on her own:
What do you think the GDP and population of the empire were in 1939?
Hint: bigger than the Soviet Union and Germany combined
