It is no suprise to me.
But why should the US govt support them with contracts and not spend our tax dollars on domestic companies that would boost our economy and jobs ?
There's no reason they have to move their entire headqaurters to dubai. It doesn't pass the laugh test. They could just as easily open an business affiliate there. That's what Exxon, Chevron, and BP do.
I think that halliburton wants to do business with Iran. There's a lot of money to be made in Iran, but there are a lot of trade sanctions and laws in the U.S. that prohibits certain kinds of business transactions with iran.
Moving corporate HQ to Dubai probabaly allows them to skirt US law, vis a vis iran. And there is a TON of money to be made in iran: pipelines, fied development, etc.
