Far Eastern countries don't appear to have terrorists who kill 3,000 innocent people at a time, or attempt to blow up transatlantic airliners tho', do they.
USA has to be forgiven for what appears to be paranoia after what they suffered. Put up with it, or don't go there. The security will not change.
It's merely half an hours grief. I cannot understand why so many people get so upset by it. If you think you're having a bad day, then I can assure you that there are people in the world having to put up with much more than a little security delay.
