Those existing relationships include causality, influence, proximity, temporality, and much more. Why single out "influence" as a privileged kind of relationship?

Second, your example in your original post was of finding out if there was a causal relationship between the Cold War and 9/11. Wqell, I think this example actually points out the artificiality and arbitrariness of how this would end up being used if it existed as a separate feature.
Correlation does not imply causality.
What *would* be cool, and might just be a different implementation of exactly what you have in mind, would be a tool to find all the (reasonably short) click-paths between any two concepts. I mean, now that I selected the article titles randomly, I actually wonder how many clicks it takes to get from Marie Antionette to Michael Jordan. And what's intervening?
Over a year ago I raised the possibility of tracing every article back to the Main Page. None in my random sample was more than five links away. Thus if you trace Marie Antoinette and Michael Jordan back to the Main Page, the sum of their links will be a maximum distance. :-)
