Possesive nouns

[JbhB682]

Hi - my understanding of possessive nouns is that X's Y is the same as Y of X

Example
X's Y
example 1) Apple's success was due to the iPhone
example 2) Sam's income was doubled

Y of X
Reworded 1) Success of Apple was due to the iPhone
Reworded 2) Income of Sam was doubled

However why can't I do the same with the following ?

Britain's exploitation of Africa included forced labor

How can I re-word into Y of X ?
Possibility 1) Exploitation of Britain of Africa included forced labor

Is that a viable re-wording ?

Reason - it's based on an OG problem ( i can't type it out but its the Nellie Bly problem)

In simplest terms, probably because there's already another "of" there that's used in a non-possessive way. For another example:

Best as-is: Marielle's tower of cupcakes won the prize for best dessert.
Weird, but maybe not wrong: The tower of cupcakes of Marielle won the prize for best dessert.
Wrong: The tower of Marielle of cupcakes won the prize for best dessert.

No, because that phrasing makes it sound like Britain is being exploited. I think this may be an exception to the "of" possessive pattern you noted in general above because of the idiomatic way that "exploitation of" is used: The exploited party, not the exploiter, follows the "of."

I think you'd have to word it this way:
The exploitation of Africa by Britain included forced labor.
