I cannot accept that at all. May be some of today's Jews have felt unthreatened in their own society but Jewish history is one of Jewish exceptionalism only as victims.
Someone here has written about something "two wrongs don't make a right". but it's not just that. If Jewish people are experiencing anti-Semitism because of Israel's actions that must mean that anti-Semites now feel free to express their anti-Semitism openly. That's a big worry.
Israel has taken upon itself the leadership of Jewish people, their diaspora, around the world, even if the majority of those Jewish people don't want Israel to represent them in any way whatsoever. But they'll now be tainted by the murderous behaviour of Israel, and increasing anti-Semitism is the direct and predictable result of all this violence inflicted on Palestinians. But in some ways, this actually suits the Zionist cause - victimhood is their rationalisation and fig leaf for their own misbehaviour. If Zionists really cared for Jewish people, they wouldn't behave in a way that brings these people distress or in Israel serious danger.
