With a PoD no earlier than 1897, what changes to how (or whether) the Dreyfus Affair unfolded would have the biggest changes on France in the years leading up to the Great War?
Some background -- Dreyfus, TTL, is still arrested for treason in 1894, and is sentenced to Devil's Island in January 1895; TTL also still has the new French Director of Intelligence discover the real culprit in August 1896, upon which he is still silenced by being transferred to Tunisia in November of that year. (Lazare also likely still publishes A Miscarriage of Justice that same month.) Now, OTL saw Zola publish J'Accuse in January 1898, President Loubet pardon Dreyfus in 1899, and his official exoneration in 1906 -- and more still, all lending to a watershed moment for French and Jewish identity.
