France has summoned Charles Kushner, the United States ambassador and Ivanka Trump's father-in-law, after he sent a letter to President Emmanuel Macron criticizing France's approach to combating anti-Semitism. Kushner urged Macron to take stronger action against hate crimes and accused the French government of emboldening extremists through its public statements and gestures towards Palestinian statehood. The French government responded by calling Kushner's allegations 'unacceptable' and 'inflammatory', stating that his letter interfered with France's internal affairs and violated international law. The incident has highlighted growing tensions between France and the United States over policy towards Israel and the rise of anti-Semitism, with both governments defending their respective positions.
