What Would be the Largest Plausible Sphere of Influence for the Western Allies Post WWII?

Depending on when you're allowing a POD, I think a united and Western oriented Germany might be pushing up against that upper limit pretty damn well.

Maybe a successful RoC and a united, Western oriented Korea, too.
 
The whole of Europe, nay, the WORLD!
If the Soviets lose or are severely, much more severely than OTL, mauled, then there's no counterbalance to the WAllies. Unlikely, but still possible.
 
Alliance?
