If the Israeli's wanted/needed a liquid ban to benefit aviation security, they would have instituted such a policy long ago, having known about the concept and possible threat of liquid explosives for a long time. They would not play games with security as a knee-jerk reaction to a newly uncovered "terrorist plot".

So, no, it is business as usual at TLV and it remains the airport in the world with the "best" security-- despite the lack carnivals.

Also, El-Al didn't switch to plastic butter knives after 9/11 either-- the Israeli people have enough real security to worry about that they don't have time for this type of BS, as others have noted.
