Pentagon's Leading Russia-Ukraine Expert Departs Amidst Political Transition

Laura Cooper, the Pentagon's leading expert on Russia and Ukraine, has stepped down from her position just days before President-elect Donald Trump takes office. Cooper, who has been a key player in coordinating U.S. military aid and marshaling international support for Ukraine, left her post at the beginning of 2025. Her departure marks a significant moment in the ongoing geopolitical tensions between the United States, Russia, and Ukraine.

Cooper has served in the Pentagon for over two decades, most recently as the Deputy Assistant Secretary of Defense for Russia, Ukraine, and Eurasia. She played an instrumental role in coordinating large-scale deployments of U.S. military aid to Ukraine following Russia's full-scale invasion in 2022. Her efforts have been crucial in establishing strong relationships with Ukrainian government officials, and she is regarded in Kyiv as an "honest broker in negotiations."

Her departure from the Pentagon reflects a growing sense of anxiety within the Defense Department over the incoming administration and its potential impact on career civil servants and military flag officers. Pentagon and State Department officials who worked closely with her expressed fears that she might face persecution during Trump's presidency for her testimony and ties to Biden-era Ukraine policy.

Cooper first gained media attention in 2019 when she was summoned to testify before Congress about former President Donald Trump's attempts to pressure Ukraine into investigating Joe Biden. Her testimony focused on the delay in providing Ukraine with $400 million in military aid allocated by Congress for training purposes. She stated during the hearings that the funds were "held without explanation," and U.S. officials "began to raise concerns about how this could be done in a legal fashion."

Her duties at the Pentagon are currently being temporarily handled by Steven Schleien, the head of the Office of Defense Continuity and Mission Assurance, which ensures the uninterrupted functioning of the U.S. administration in crisis situations. Schleien's role is to maintain stability and continuity within the department during this period of transition.

Cooper's departure comes at a critical time for U.S. foreign policy. The Biden administration is set to announce a substantial final weapons aid package for Ukraine as part of Defense Secretary Lloyd Austin's visit to Germany. This package aims to provide Ukraine with the necessary resources to defend itself against ongoing Russian aggression.

As the political landscape shifts with the incoming Trump administration, the future of U.S. support for Ukraine remains uncertain. The departure of Laura Cooper, a steadfast advocate for Ukraine, underscores the challenges and uncertainties that lie ahead. Her expertise and dedication will be missed, and her absence leaves a significant void in the Pentagon's Russia-Ukraine office.

Laura Cooper is heading to a teaching position at the National Defense University in Washington, where she will continue to contribute her expertise and experience to the next generation of defense professionals. Her departure marks the end of an era for the Pentagon's Russia-Ukraine office, but her legacy of dedication and service will undoubtedly continue to influence U.S. defense policy.

The departure of such a key figure highlights the importance of continuity and stability within the Defense Department. As the U.S. navigates the complexities of international relations and geopolitical tensions, the expertise of individuals like Laura Cooper is invaluable. Her contributions have helped shape U.S. policy and support for Ukraine, and her absence will be felt by those who have worked closely with her.

The Biden administration's final weapons aid package for Ukraine is expected to include advanced military equipment and training resources. This aid is crucial for Ukraine's defense efforts and demonstrates the U.S.'s commitment to supporting its allies in the face of aggression. However, the incoming Trump administration's stance on this aid package remains unclear.

As the U.S. prepares for the transition of power, the departure of key figures like Laura Cooper raises questions about the future direction of U.S. foreign policy. The incoming administration's approach to Russia and Ukraine will be closely watched by international observers and allies. The decisions made in the coming months will have far-reaching implications for global stability and security.

The Pentagon's Russia-Ukraine office will need to adapt to the changes brought about by Cooper's departure. The expertise and experience she brought to the role will be difficult to replace, and the office will need to find ways to continue its important work in her absence.
