Aspirations Amidst Uncertainty: The Ten-Year US-Ukraine Security Agreement

Exploring the potential and challenges of the new U.S.-Ukraine security agreement amid growing political uncertainty

As leaders gathered in Washington for the NATO summit, Ukraine was unsurprisingly at the center of many of the alliance’s discussions. Russia’s full-scale invasion has, in many ways, galvanized the alliance and led to renewed promises that Ukraine would be given a pathway toward membership. But despite Kyiv’s entreaties for a speedy ascension, membership seems far from imminent, underscoring the practical importance that long-term military assistance will play in Ukraine’s ability to sustain its war effort. In the shadow of Ukraine’s long war and a growing consensus that it is likely to persist for the foreseeable future, Presidents Biden and Zelensky recently inked a Bilateral Security Agreement, outlining a ten-year framework for military assistance and cooperation. But given the uncertainty surrounding how a potential change in the White House could impact Ukraine’s war prospects, it is worth considering the agreement’s immediate and long-term implications for the U.S.-Ukraine partnership.

What Is in the Agreement

The “Bilateral Security Agreement Between the United States of America and Ukraine” represents an expansive vision for bilateral cooperation. While it outlines principles and intentions for the partnership in economic and political fields, at its core the agreement focuses on steps the U.S. and Ukraine will take to deepen their defense partnership, centering the provision of U.S. “materiel, training, and advising, sustainment, intelligence, security, defense industrial, institutional, and other support.” More specifically, the agreement lays out a spectrum of priority areas for the “development and transformation” of the Ukrainian defense sector, highlighting key combat domains, sustainability and domestic industrial capacities, and Ukraine’s integration with NATO.

Critically, the agreement spells out shared commitments to address the risk of diversion emanating from the historically large aid effort, including pledges to deepen and expand collaboration on meeting End-Use Monitoring requirements in an especially challenging environment.

The agreement also dedicates a significant portion of its text to the intensification of Euro-Atlantic integration. Going beyond security, the document notes that both parties will cooperate on reforms that align with Ukraine’s efforts to join the European Union and meet requirements for NATO ascension. 

Further, the agreement provides for a consultation mechanism in the event of future Russian aggression. It falls short of any obligation or promise for either party to respond directly but lays out terms for meeting urgently to determine and coordinate an appropriate response.

What Is Not in the Agreement

Despite its length and the loftiness of its ambitions, the agreement remains fairly general and offers little by way of new or specific commitments. In effect, it is a useful summation of the Biden Administration’s existing approach to Ukraine and lays out a trajectory for expanding defense collaboration along key lines of effort, providing some structure for an enduring Ukraine aid that goes beyond the immediate demands of the frontline.

What it lacks is much specificity – aside from brief references to Patriot Missile Systems and F-16s, it makes no mention of other platforms and offers general aims for improving Ukraine’s defense capabilities in key areas. Similarly, the agreement does not mention any specific level of assistance, either in financial or other concrete terms. In other words, while the agreement lays out far-reaching goals for security cooperation with Ukraine, the ways and means of achieving them remain less clear.

What the Agreement Means in Practice

The agreement is a useful political signal for both the Biden and Zelensky administrations. U.S. assistance has been and will continue to be indispensable for Ukraine – Washington is by far the largest single contributor to Ukraine’s war effort, providing over $51 billion in military aid since February 2022. In the aftermath of a months-long political fight in Washington to authorize new assistance, and as questions persist about Ukraine’s endgame amidst increasingly stagnate frontlines, the ten-year agreement represents a demonstration of diplomatic unity from both sides.

But much of the agreement’s practical impact will depend on political developments in Washington. The agreement itself represents political commitments; it does not carry the force of a ratified treaty or formal alliance. It is, in practice, non-binding, and creates no concrete obligations for either side. Even in the event of a second Biden term, meeting the goals of the agreement would still require Congressional appropriations, which have proven increasingly difficult to achieve in recent months. Given President Trump’s strong skepticism of continuing military support for Ukraine and the divisiveness of the topic on the Hill, the agreement may be more aspirational than practical.

Conclusion

The “Bilateral Security Agreement Between the United States of America and Ukraine” offers a broad overview of a potential future for defense collaboration between Washington and Kyiv. Though general, it remains ambitious in the capabilities, reforms, and progress both parties hope to realize for Ukraine. But commitments spelled out in the agreement will be subject to changing political dynamics in Washington over the short and long term. Congressional enthusiasm for allocating extensive additional support to Ukraine has shown signs of wavering, while President Trump has indicated that his potential re-election could pivot U.S. policy dramatically away from its current trajectory. Given these uncertainties, the agreement emerges more as a tentative vision than a definitive plan, contingent upon an increasingly unpredictable political climate in Washington.
