Ukraine’s fight against Russia’s ongoing invasion is often framed as a referendum on Western resolve, but the real test is whether the Ukrainians themselves can sustain a credible defense posture over time. As the war enters a fifth year, Ukraine’s long-term security will depend less on promises from abroad than on decisions made at home.
Ukrainian President Volodymyr Zelenskyy’s recent diplomatic push reflects this reality. Throughout 2025, he intensified efforts to shape a settlement that would not simply freeze the front, but also create a durable security framework. He did so knowing that any peace will be judged by its ability to prevent a future renewal of Russian aggression.
Crucially, peace through strength must mean the strength of the entire nation, not half of it. Ukraine’s security cannot rest on external guarantees alone. It must also be based on national capacity, including a cultural and institutional shift that integrates women as a pillar of defense planning. This is not a social policy argument. It is a force generation argument.
Even in an optimistic scenario, any agreement between Kyiv and Moscow will demand long-term readiness and self-reliance. Ceasefires can be violated. Commitments can erode. What endures is force posture: Trained units, predictable rotation, and the resilience to absorb pressure.
Deterrence is not a document. It is a condition and it rests on how effectively a state mobilizes and prepares its population. Yet Ukraine’s mobilization still reflects post-Soviet assumptions. Men between the ages of twenty-five and fifty-nine are treated as the default defenders of the state, while women are viewed as supplementary. That division no longer matches battlefield realities or Ukraine’s strategic needs.
Since 2024, Kyiv has tightened mobilization rules, expanded enforcement, and narrowed exemptions. These measures have stabilized force levels, but they have not solved the underlying problem: Ukraine is fighting a prolonged war of attrition against a far larger adversary. Pulling more men into the system without changing how the system functions will not produce sustainable results.
One weakness is preparation and allocation. Many men still only receive limited training before mobilization. At the same time, tens of thousands of women with in-demand support skills in fields such as logistics, communications, medicine, intelligence, engineering, IT, and drones, remain outside the recruitment and training pipelines.
The result is inefficiency on two fronts. Front line units are overstretched and denied predictable rotation, while rear area roles are often filled by personnel whose skills are misaligned with their assignments.
