Ukrainian Defense Minister Oleksii Reznikov submitted his resignation today, marking the biggest change in the defense institution since the war with Russia began 18 months ago. Reznikov led Ukraine's efforts to pressure for Western weapons to combat the Russian invasion, but his resignation following months of corruption allegations against his ministry is not expected to significantly impact military operations. President Volodymyr Zelensky announced yesterday that he dismissed Reznikov and suggested that Rustem Umerov, a member of the ethnic Crimean Tatar community and a former parliamentarian who heads the State Property Fund, should succeed him. Reznikov, who took office in 2021, helped Kyiv secure billions of dollars in Western military aid since the Russian invasion in February 2022. Andriy Zahorodnyuk, who served as defense minister in 2019 and 2020, told Reuters, "Reznikov did a great job building relationships with other ministers and departments... He saved the country because he was instrumental in organizing weapon shipments and so on." Although Reznikov, a 57-year-old former lawyer, was not personally implicated in the corruption allegations leveled by Ukrainian media against the defense ministry, especially regarding procurement, the accusations sparked calls for his dismissal, and Reznikov portrayed himself as a victim of a smear campaign. Zelensky stated he does not tolerate corruption at a time when Kyiv is trying to advance its European Union membership ambitions and demonstrate adherence to the rule of law. He added that the defense ministry needs "different forms of interaction with the army and society as a whole." Ukrainian political analyst Volodymyr Fesenko remarked, "It makes sense to remove the growing tension regarding the ministry," referring to the long-standing calls for Reznikov's removal.
