Counterfactual

Considering the world economic picture in the second half of the 20th century and the first years of the current century, what would it have looked like if Japan had been granted limited surrender to end WWII?

That is, had the imperial and militarist systems been allowed to survive--along with the status quo ante bellum--surely Japan would have been drastically different from the ground-up reconstruction in our image that followed the war.

Unconditional surrender, then, was our fondest wish but has been our 50-year nightmare.
