If it was a straight out slogfest i think that eventually the Allies (Britain, France and Czechoslovakia) would win, if and only if they took on an offensive role and not merely a defensive role, but we have some radicals within the equation and they are Italy and Poland, I know Poland had its sights on gaining Czech territory (Possible German/Polish Alliance) and Italy with its pact of steel with Germany.

Interesting amount of possibilities could occur.
