The U.S. ambassador to Hungary is the latest American official to earn the Kremlin’s ire over remarks he made last week publicly deriding Russian President Vladimir Putin as a “small man” and “a holdover from a time that most of the world has tried to move beyond.”In a speech on Jan. 6 commemorating the 45th Anniversary of the Return of the Hungarian Holy Crown, Ambassador David Pressman took the opportunity to slam Russia’s war as the product of “tyranny” and “authoritarianism” before taking a jab directly aimed at Putin.They had already charted their course, and it did not include a return to a broken, abusive system that had failed them for so long.”Russian officials, it appears, have not taken well to the remarks.In a Telegram post on Tuesday, the Russian embassy in Hungary went on a tirade against Pressman’s “unacceptable” remarks about “the personality of a foreign Head of State,” calling his comments “an outrageous violation of basic diplomatic protocol and practice,” according to Russian state news agency TASS.In an extraordinary show of pettiness, the Russian officials proposed that Pressman “make up for the lack of professionalism in the field of diplomacy” by reading “a famous book by the ‘patriarch’ of American foreign policy, Henry Kissinger, which is conveniently entitled Diplomacy.” The Russian diplomats even went so far as to provide a link to a Hungarian bookstore that sells copies of the Kissinger book.According to Politico, Pressman has been a go-to target of criticism from the country’s state media outlets for calling out the Hungarian regime’s propaganda—and even making cheeky comparisons between comments made by Hungarian officials and Putin."
