In an escalating international dispute, Israel launched a series of diplomatic attacks against several of its Western allies as they prepare to recognize a Palestinian state next month.

Prime Minister Benjamin Netanyahu sent two strongly worded letters to the leaders of France and Australia, accusing both men of fueling antisemitism with their decision to recognize a state of Palestine. In both letters, Netanyahu cited antisemitic and anti-Israel incidents that occurred in recent months, linking them to the governments’ positions on the Gaza war and Palestinian statehood.

“Your call for a Palestinian state pours fuel on this antisemitic fire”, Netanyahu wrote in a letter obtained by CNN to French President Emanuel Macron on Tuesday.

“It is not diplomacy, it is appeasement. It rewards Hamas terror, hardens Hamas’s refusal to free the hostages, emboldens those who menace French Jews and encourages the Jew-hatred now stalking your streets.”

The acrimonious letter drew a sharp rebuke from the Elysee Palace, which noted that Macron first learned of the Israeli letter through the press before receiving it through diplomatic channels.

France “protects and will always protect its compatriots of the Jewish faith,” the Elysee Palace said in a statement. “These times demand seriousness and responsibility, not confusion and manipulation.”
