Possessive apostrophe usage: why not "World's Health Organization"? [duplicate]

apostrophe

I am wondering why some possessive nouns does not have apostrophes.

If "America's Credit Union" has an apostrophe, why not "World Health Organization"?

My intuition says that the apostrophe is only needed if the noun refers to a specific being. In the above example, "America" refers to a specific country, and "world" is somewhat vague, as does not exist such entity called "world".

Is this correct? What would be the formal explanation?


Solution 1:

It is the formal name of the organisation. End of.

Organisations can and do choose names without regard for grammatical rules. Not that I am saying that this name is ungrammatical. My point is that rules do not apply to names.
