What is the concept of breakout capability in the context of nuclear proliferation?

Breakout capability refers to a state's ability to rapidly develop and produce nuclear weapons, despite being a non-nuclear weapon state or having limited nuclear capabilities. It involves the acquisition of the necessary technology, materials, and expertise to build nuclear weapons quickly, often in violation of international non-proliferation agreements. Breakout capability is a significant concern in international relations as it poses a threat to global security and stability, as well as the effectiveness of non-proliferation efforts.
