The chapter examines President Biden’s policy on Russia and the war in Ukraine, highlighting the administration’s reliance on outdated stereotypes and misjudgment of Moscow’s motivations. It argues that Russia’s primary concern was not NATO expansion but apprehensions about Ukrainian-style “color revolutions” threatening its political regime. Biden’s cautious approach, including limited military support to Ukraine, reflected fears of provoking Russia to use nuclear weapons. This self-deterring posture emboldened Russian aggression and hindered Ukraine’s ability to reclaim its territory. The study examines how Biden’s personality traits shaped his administration’s approach to the US deterrence strategy and impacted the pace and scope of Washington’s response to Ukraine’s military needs.
