But overwhelming victory and unconditional surrender were the foundations for that reconstruction. There is really no way that peace could have been achieved with WWII Germany and Japan through giving money or diplomacy (Neville Chamberlain says hi). Once there was overwhelming victory resulting in unconditional surrender, then the rebuilding process started.

EDIT:

In addition, there was no equivalent of the Marshall Plan between the Soviet Union and East Germany, yet there were not wars between them after WWII.
