What then? The war in central Europe (ETO) could have gotten our full
resouces, D Day would have been a year earlier and the war would have
been
over a lot sooner, German troops in No. Africa and the MTO would have
simply
been isolated and would died on the vine. Why not?

Mainly because we would have been handed our heads, trying to invade in
mid-1943. The short reason would be that the Sovs wouldn't have whittled
down the Wehrmacht enough at that point to make a Western Front possible.
Also the Brits wouldn't go. Churchill and the Imperial General Staff were
scared stiff of a direct confrontation with the Wehrmacht based on their
experience in 1940.
