The only thing the EU has - supposedly - balked at is free-for-all US data trawling.
But otherwise, all of the details that have been listed, and very possibly a few we don't know about, are being sent over with every flight.
And - let's be clear about this - this is political. It's about identifying dissenters. There may be some effort to find Muslim extremists, but that's a handy extra, not the main point of the exercise.
I think the EU should simply have said that the information isn't available. Or - as a fall back position, as you suggest - let passengers decide if flying to the US is worth giving immigration these details.
Rolling over isn't setting a good precedent for future negotiations.
I think there's already a sizeable minority who are wondering if travel to the US can possibly be worth it.
And if anyone's thinking of going to ChicaKOS - how does it feel to know that you will be tagged and filed by definition, just for attending?
What in the world needs to happen for the EU to declare diplomatic war on the US? Those whom the Gods wish to destroy They first make mad. -- Euripides
