The problem is still larger than just this one instance
Even if it happened exactly as you remember it, the problem IMO still isn't Halliburton, per se. It is that corporations are able to say, "That corporation that is entirely owned and controlled by this corporation really isn't the same entity at all. Nope, that's not us." Any time a nation passes a law saying, "You can't do that," corporate lawyers challenge them to define "you". No matter who the "you" is, the one doing it is never the one the law applies to.
