| Summary/Abstract |
Prior to the onset of Russia’s invasion of Ukraine, experts predicted an extensive cyber conflict. However, to date the scale of known cyberattacks has been quite modest. Pundits suggest that Ukraine’s improved cyber defenses, which it developed through its close cooperation with Western partners, is one of the possible explanations for Russia’s limited cyber front. This article interrogates this claim, outlining two plausible reasons for the limited effectiveness of Ukraine’s cyber defenses in the Kremlin’s limited cyber front. First, despite an extensive outpouring of cyber knowledge and expertise from the West, Ukraine’s cyber capabilities are still organizationally and operationally underdeveloped. Second, limited fungibility of cyber capabilities complicates interoperability between any joint operations and diminishes the West’s willingness to share their time-limited cyber tools with Ukraine. By explaining the challenges of interstate cooperation in the cyber domain, this article contributes to the literature on the role of alliances in modern warfare.
