Were 1200 Jews killed even collectively in these attacks? Never mind in a single day? Because that's what just happened in what you describe as "the only place it's safe to be a Jew." To say nothing, of course, of the many other attacks that have taken place in Israel over the past couple of decades. To be clear, I'm not arguing against the existence of Israel, I'm arguing against some of the assumptions about what it is or how it should operate.
I'm also pretty sure I'm not arguing with any facts. But I don't think the solution to this problem is a military one. At least not entirely. Hamas needs to be removed/destroyed. No argument from me. But to end this conflict, the blockade needs to end. It should be obvious to anybody who's paying even a little bit of attention that there will never be stable peace while 2 million people are blockaded in the Gaza strip right next-door to Israel.
Israel will need to make concessions. So will Palestine. And these will need to be made at the negotiating table, not through the crosshairs of a rifle. That's my (and many other people's) suggestion. And I guarantee you, if there's ever lasting peace in the region, it'll be because somebody took it.
