It matters because nuclear security is only as strong as its weakest link; if one country has loose security, radioactive material could be smuggled across borders. The IAEA is the main group that helps countries lock down their materials, but they are currently operating on an unpredictable budget. If this resolution leads to more stable funding, the IAEA can better train guards, install better sensors at borders, and track radioactive sources worldwide.

Without this support, the IAEA's security efforts might remain reactive rather than proactive. In a world where some groups are actively trying to get their hands on nuclear waste or materials for "dirty bombs," having a well-funded international watchdog is a key part of preventing a global catastrophe.
