I don't think that's the question. The question is do you have a system, not the level of security. You are confusing two different issues--the system and the level.
I agree that Israel has a very, very high level of security, which it needs, but the system fundamentally should be the same. I can describe it to you as the volume on your radio. You have a system that works, and if your threats go up, you just turn up the volume button. You don't change the way you do your screening. You don't add equipment. You don't retrain your people. You don't invest in your airport security every year because other incidents have happened. You are running after the incidents instead of being in front of them.
Israel has never banned liquids. Israel has never looked at what people carry onto the airplane other than what the ICAO has banned. And we have never had any problem in the last 25 years...although I can tell you that we have 70 threats, real-time threats, which means that within two hours, somebody will blow something up near the airport or in the airport. And we never had an incident like that.
I agree that the level is very high. The system should be the same. Now, we're not profiling. I don't even suggest to you profiling. I don't even suggest you go to the system that we have in Israel of interviewing passengers. I suggest that instead of looking at everybody, create a trusted traveller and trusted worker identification process, in which travellers who would like to walk through security very fast would actually surrender some of their information to the authorities and be--as you wish--pre-screened as trusted travellers.
Once you have done this, you will tremendously reduce the number of people you have to check. Your checkpoints then become a very fast walk-through.
You do need cameras to watch who is coming into your airport, what kinds of cars, who is doing what, who is coming into your terminals, what's going on in the terminals, and then, of course, what's going on at the sleeves to the airlines.
We can argue until tomorrow whose system is better, but I think we have the proof that it works.
