Repairs at key missile sites began soon after they were hit by Israeli and U.S. strikes last year, but work at Iran’s nuclear facilities has been slower.

President Donald Trump called for U.S. nuclear experts to create a new modernized treaty to replace the New START nuclear arms agreement with Russia via Truth Social.

Despite Iran’s three main nuclear facilities remaining inoperative, images show visible work underway. Iran seems to have repaired some ballistic missile facilities damaged in strikes last year,

Russia has repeatedly struck Ukraine's energy infrastructure, risking a nuclear disaster.

LONDON/WASHINGTON, Feb 6 (Reuters) - The Trump administration's plan to unleash a wave of small futuristic nuclear reactors to power the AI era is falling back on an age-old strategy to dispose of the highly toxic waste: bury it at the bottom of a very deep hole.

The New START treaty has expired. For 15 years, the treaty served as an agreement between the United States and Russia to limit deployed nuclear weapons; its expiration signals the end of the old nuclear arms control regime and portents the world’s entry into a dangerous new period of unconstrained arsenals.

Centrus Energy ( LEU 3.23%) is one of the few U.S. companies licensed to sell low-enriched uranium (LEU), the fuel used in most commercial nuclear reactors. It's also the only publicly listed U.S. company that produces high-assay, low-enriched uranium (HALEU) for advanced nuclear reactors. That makes it a linchpin of the nuclear energy market.
