Do you mean that they have lobbied virtually all countries though, or what? I don't understand how they can be so dominant on a kind of global scale. I suppose there may be some places where they are not (I.e. North Korea, and a few other outliers) but I would assume they do have a certain amount of broad, global reach. Have they really just managed to bribe/make "friends" with (almost) every country on the planet?
Like everywhere: lobby and corruption. Works like a charm. Being based in the "World policeman" also helps.
