Delaying war until Germany was ready also gave Britain and France more time to rearm. Their growing production made readiness a moving target for an Axis power with a smaller industrial base. One proposed explanation for Hitler's continued pressure is that someone in his circle recognised this worsening relative position. The argument about France in 1940 likewise stresses the collapse of confidence before the remaining forces could be reorganised. That is an interpretation of the campaign's vulnerability, not proof that an extra year would have guaranteed a different result. More time would improve the opponents' preparations as well as Germany's.

Why waiting did not solve the Axis industrial disadvantage
Axis rearmament had to keep pace with larger opponents, so postponement could make the relative balance worse.
