The anti-corruption drive launched by Ukraine over the past few days is long overdue. But while positive, it will have little lasting effect unless Ukrainian President Volodymyr Zelensky’s government maintains this action and targets midranking officials as well as those at the top.

Corruption in Ukraine is, or at least should be, a top concern for the U.S. government. While Ukraine deserves the U.S. aid it is receiving (the European Union should be, but isn’t, matching U.S. aid levels), any tolerance of corruption is utterly unacceptable. American taxpayers rightfully expect their money to be spent prudently in pursuit of a single objective: the survival and success of Ukraine’s democracy against Russian imperial aggression.
