Semantics.

The use of the word "For" doesn't strictly imply that something is done solely in tune with a specific purpose, rather that it was done with that purpose in mind, and could have been precluded with other goals as well.

The fact that you've openly admitted that oil may have been a factor in determining whether or not at least two wars throughout history would have occurred basically says that you understand this, but are overlooking it in an attempt to prove that you know something on the subject.
