Can the Nuclear Non-Proliferation Treaty prevent a disaster?

The Nuclear Non-Proliferation Treaty, with 191 signatories, is based on the principle that countries without nuclear weapons should not acquire them, and those that possess them should disarm. However, its implementation has recently stalled, prompting warnings from experts and diplomats about the heightened risk of a nuclear arms race. The United Nations chief has also raised concerns about the waning influence of this global agreement.
