Israel have the dual advantage of smaller numbers of required staff plus higher risk of terrorist activity (which leads to better investment into security infrastructure)
They do have a reasonably good security set up (been through Israeli airports a few times now) but they do have issues/idiots too (who doesnt). They have a reasonable trade off of privacy over security.
For a larger country with lower risk cheap options such as body scanners are a "solution" because they theoretically require lower skilled staff to spot a terrorist.
Of course the theory is poor in the first place and the execution worse (so far)
From the post, it sounds like they have better trained employees with more racial profiling. That level of racial profiling, even though it probably does work, would not be accepted in the US.
