If American officials have to deal with "a hundred different languages," then how do customs and immigration staff manage to do it? If they can, why can't screening staff? And I would assume Ben Gurion staff would also have to deal with Russian, Spanish, French, German (after all, it's the Christian holy land as well), and even Chinese from time to time.
Immigrations, and customs don't engage in conversation every passenger they deal with. Under the Israeli system TSA personnel would have to, and if they couldn't communicate they would hand search those passengers. and their bags. At an airport like LAX or JFK that would be a nightmare. It's safe to say that the US is a bigger tourist, job, and educational destination than Israel is...and from all corners of the globe. IMO it's not practical to implement a security system that works for a country the size of New Jersey, and has only one airport, and expect to work in a country that has a zillion airports, and fills up half of an entire continent.
