It should be. It's just that most people don't have the faintest idea of what it's all about.
I suppose one reason is that Spain (Cintra's country of origin) does not support the insurgents in Iraq, nor do they help Iran realize it's nuclear ambitions, as UAE was said to be doing by one FNC talking head. And, as far as I know, Spain has no problem recognizing Israel.
Another reason, I suppose, is that it's a highway, not a port, which means it's a transportation corridor, not a place of entry into the U.S., which is where the security concerns should be, so that everything within the country remains free.
