Claim: Belarus is preparing its missiles to carry nuclear warheads under a new program.

Based on what we could find, the claim that Belarus is preparing its missiles to carry nuclear warheads under a new program holds partial truth with significant nuances. Mainstream sources confirm Belarus is actively modernizing and expanding its missile production capabilities, with official statements indicating exploration of nuclear warhead integration with Polonez missile systems.

However, Belarus historically disarmed its nuclear arsenal, remains officially non-nuclear, and allows Russian nuclear weapons on its territory, complicating the narrative. The strongest evidence lies in recent high-level security official statements reported by Reuters, which suggest at least exploratory steps toward nuclear-armed missile capabilities.

Limitations include the lack of independent confirmation of warhead production, Belaruss limited missile industry experience, and geopolitical reliance on Russian nuclear deterrence. Alternative expert analyses and technical reports do not corroborate active Belarusian nuclear warhead development, emphasizing Russias role in regional nuclear security and skepticism about Belaruss standalone nuclear ambitions.

The claim thus reflects an evolving security posture with possible preparatory activities but no clear evidence of an advanced or operational nuclear missile program. Final verdict: the claim is partially true, requiring careful contextual understanding and ongoing monitoring given the strategic implications.
