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.
