the security concerns are the basis for the opposition. you refuse to believe those are even possible, so what's to talk about.
That's simply too vague. There are security issues with any company and there's no reason to believe that they're more acute with a UAE company--unless one simply doesn't trust Arab people. Numerous posters have suggested logical reasons why we are not at increased risk if we go with a UAE company.
So, given quite a few chances, you've failed to offer anything concrete. Maybe someone will think of something tomorrow, but for now I trust that the President and his people have explored this thing pretty thoroughly, just as carefully as they explored the need to move on Iraq.
