Well even if having the resources of the largest colonial empire in history wasn't enough to allow the UK to win a war in 1938, what about in 1933? 1934? 1935-37? When the Germans seized the Rhineland in '36 they could have been easily steamrolled by a French-British alliance and that would have been the end of Nazi Germany then and there. Nazi Germany was only able to become the juggernaut it was because of the years of appeasement leading up to that point and I think we can agree by the time they became an apparent threat it was already too late. What I'm saying is if the parallel holds with China today, we are barreling towards 1938 at alarming speed and this time I don't think the world can afford to be wrong again.
