Terrorism has not defeated Israel in the past, writes David Horovitz about yesterday’s synagogue murders. Palestinians leaders should have learned that by now.

Because the final thing that has to be put in writing, even on a horrible, evil day like this, when the fingers loathe the necessity to tap the keyboard, is that it’s not going to work. Palestinian terrorists, and those who incite them and support them, should know: we are not going to be shot and stabbed and bludgeoned out of here by your brutality and the false justifications you invoke to legitimate it.

We stood firm during year upon year of second-intifada terrorism, when you were blowing up our buses, malls, restaurants, and supermarkets, and pragmatism could have dictated that we do what the terrorism was designed to make us do: flee. We do not insist on maintaining our majority Jewish state to the exclusion of your rights. Anything but. We seek co-existence. But your rights cannot be achieved by denying us ours. For this is the homeland of the Jewish nation, the only place we have ever been sovereign or sought sovereignty. And what needs writing and saying, most especially on a terrible day like today, is that we will not be driven from it.

Two extraordinary events demonstrate something important about Israel’s most fervent adversaries. One was a speech given at something called The People’s Forum (funded generously by Goldman Sachs), which stated, “When the state of Israel is finally destroyed and erased from history, that will be the single most important blow we can give to destroying capitalism and imperialism.”

The suggestion that this tiny state is the linchpin of a global, centuries-old phenomenon like capitalism goes well beyond anything resembling rational criticism. Even if Israel were guilty of genocide, apartheid, and oppression—which of course it is not—it would not follow that its destruction would help end capitalism or imperialism.

The other was an anti-Israel protest that took place in front of New York City’s Memorial Sloan Kettering Cancer Center, deemed “complicit” in Israel’s evils. At organizers’ urging, participants shouted their slogans at kids in the cancer ward, who were watching from the windows. Given Hamas’s indifference toward the lives of Gazan children, such callousness toward non-Palestinian children from Hamas’s Western allies shouldn’t be surprising. The protest—like the abovementioned speech—deliberately conveyed the message that Israel is the ultimate evil and its destruction the ultimate good, cancer patients be damned.

The fact that Israel’s adversaries are almost comically perverse does not mean that they can be dismissed. If its allies fail to understand the obsessive and irrational hatred that it faces, they cannot effectively help it defend itself.
