Commander: Europe at war - lost campaign

I've been playing Commander: Europe at war on the Sony PSP since the weekend, and unfortunately it looks likely the PSP player, playing as the Axis, has won world war 2.  This is partly due to bad strategy on my part, like failing to evacuate the UK and French forces from France after the fall of France and also better than expected performance from the Italians, especially on the Eastern Front.  For some reason the US has not entered the war which is a big problem in the western front.
