Is Ukraine capable of developing its own nuclear weapon?

In the midst of ongoing tensions with Russia, the question of Ukraine's potential nuclear ambitions has resurfaced. However, experts agree that the prospect of Ukraine developing and maintaining its own nuclear weapons as a deterrent against Russian attacks is highly improbable in the near term.

Technical Challenges

Ukraine dismantled its Soviet-era nuclear arsenal in the 1990s and does not currently possess the industrial infrastructure, materials, or technical expertise required to rapidly recreate nuclear weapons. While Ukraine is advancing its domestic missile and air defense technologies, these are conventional systems rather than nuclear weapons.

Nuclear weapons development necessitates sophisticated uranium enrichment or plutonium production facilities, weaponization capabilities, and delivery systems—areas where Ukraine currently lacks recognized capacity and must start mostly from scratch.

Political and International Ramifications

Ukraine is a signatory to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) as a non-nuclear weapons state and is committed not to pursue nuclear weapons development. Moving to build nuclear arms would breach these commitments and provoke severe international consequences, including sanctions, political isolation, and loss of Western military and economic support—critical for Ukraine’s ongoing defense.

The Budapest Memorandum of 1994 provided security assurances from Russia, the US, and the UK in exchange for Ukraine giving up its nuclear arsenal. Rearming would undermine these agreements and destabilize global nonproliferation norms.

Geostrategic Considerations

Russia’s nuclear threat remains acute, with low thresholds for use in retaliation to conventional attacks, increasing nuclear risk in the region. Ukraine’s nuclear development could drastically escalate tensions, potentially provoking Russia to escalate militarily or even use nuclear weapons preemptively.

Western partners, notably the US, have so far restricted Ukraine’s use of certain long-range conventional missiles to avoid escalating the conflict to nuclear dimensions.

Conclusion

While Ukraine is rapidly developing conventional military technologies and indigenous missile systems to defend itself, restarting an indigenous nuclear weapons program under current circumstances is not practical and would carry overwhelming political, legal, and security risks that outweigh any theoretical deterrent benefit.

If Ukraine were to leave the Nuclear Non-Proliferation Treaty and expel IAEA inspectors to process fissile material into atomic bombs, it could face international reactions such as diplomatic isolation and economic sanctions.

Without credible security guarantees, such as NATO membership, Ukraine could ultimately resort to "nuclear self-help" in the long run. However, the industrial requirements for the production of fissile material and the assembly of a warhead on carrier systems exceed Ukraine's current capacities. The development of a reliable carrier system for atomic bombs, along with the production of fissile material, would require significant investments and years of development.

If Ukraine were to opt for uranium enrichment instead of plutonium, even more extensive and expensive facilities would have to be built. In light of these challenges, it appears that Ukraine's nuclear ambitions remain a distant dream in the near term.
