Time for some to either butch up or clear the premises. When's the last time a non-El Al flight was targeted/took fire going in or our of TLV? When's the last time a crew bus was attacked going to/from TLV airport? Not in recent memory, that's when.
If you want to be a nervous crew member there are far more obvious places where you can exercise those tendencies.
Israel is not a war zone, far from it.
