It's a shame that the national security argument, which is really the strongest argument for or against anything that exists, is diminished in such a fashion. I mean, if one does not want a Spanish-led consortium operating a tollroad in Indiana, fine. Just don't explain to me that the Spanish will interdict U.S. troop movements in case of national emergency.
In the same fashion, don't simply point at a regulation and shout "international cooperation, bad!" There's a reason automobile bumpers are the same distance off the ground. Think about it.
Spoken like a fellow who has never been rear-ended by a Hummer.
