If this is correct then her pretext unravels. If other Jews have no issue with Israel's statehood being questioned or don't believe in its statehood, Israel's existence must be up for debate. It has nothing to do with vetoes.
Its not antisemitic to question Israel's status per se. It's perfectly reasonable to suggest that there should not be an ethnonational Jewish state when non Jewish people are native to that land.
Its quite worrying when right wing factions in Europe support Israel yet the charge of antisemitism is levelled at those wo wish for an equitable peace.
