And before you trot out that other old cliche, 'if it hadn't have happened we'd be speaking German now!" Well, if a whole HOST of things hadn't happened we could have been speaking German now, or maybe not, as the other occupied dna defeated powers are all free now and none of them are speaking German, whose to say it would not have been the same eventual outcome for us?
Because if the UK had fallen the USA would not have gotten involved in a European war without a base of operations?
And without having to have to keep troops in the west, Germany might have succeeded in conquering Russia? As with WWI, the defeat of France etc was only seen as a means of removing a threat to the rear before moving onto the the real threat in the east.
Just saying.
And just because some some historians say it wasn’t important does not make it so. 20-20 hindsight is wonderful, but as with most hindsight what is claimed to have been inevitable could well have turned out totally differently - and equally then claimed to have been inevitable. The eye witness account would seem more reliable.
I was was going to say you risk seeming pompous and insufferable. But in hindsight it seems to have been inevitable....
