Most airports and security folks would disagree. In HKG and BKK you go through security to get from arrivals to departures. In SIN you go through security before getting to the gate.
Nearly every airport I'm familiar with requires reclearing security. An airline that flies from a country with substandard security might be a sieve for a terrorist to get into the secure zone in TLV. Israeli security isn't that big of a deal if you're M.O.T. and heading to Israel.
If you're not, then it may make you think twice about taking LY thru TLV. I've heard from other people who aren't Jewish and have experienced LY's security professionals, that they'd rather increase their colonoscopy frequency than go through that again.
