What red lines haven't they crossed? Mass murder at Passover celebrations in your home town? Mass murder of people returning from prayer at the Kotel? Shooting pregnant women and babies at point blank range?
I agree they haven't yet set off a nuke in Tel Aviv, but just wait till they get their paws on a nuke.
That sentiment, about further off red lines, is unfortunate but in a way understandable psychologically.
It's like the example they use about cooking lobster. The lobster boils to death not appreciating the ever rising temperature.
Israel is so psychologically damaged, to shock them is getting harder and harder.
Imagine the response of Israel 1948-1993, to rockers fired daily into an Israeli towns.
You're both right. My choice of words was, at best, unfortunate.
Let's put it this way: at some point a Palestinian action or set of actions enrages the Israeli public so much that the government has no choice but to act. We've seen major terrorist attacks followed by major IDF operations before. Sometimes it was because an attack was particularly heinous but more often than not it's because we reached a point where we couldn't sit back any longer no matter how much Washington protested.
My point is that missiles landing in Tel Aviv would be heinous enough to provoke such a response. I am not saying that any of the attacks you have mentioned is not horrific in and of itself.
