"So, we need to delegitimize the nuclear weapon, and by de-legitimizing... meaning trying to develop a different system of security that does not depend on nuclear deterrence"

Mohamed ElBaradei's quote addresses a crucial issue in worldwide security and arms control: the reliance on nuclear weapons as a main ways of deterrence. ElBaradei, a recognized supporter for nuclear disarmament and former Director General of the International Atomic Energy Firm (IAEA), is highlighting the requirement to shift worldwide security paradigms far from nuclear deterrence.

To "delegitimize" nuclear weapons suggests to weaken their viewed requirement and acceptability as tools for nationwide security. This entails questioning and minimizing the status that nuclear weapons hold as signs of power and security warranties. For decades, the doctrine of nuclear deterrence has been based on the risk of mutual guaranteed destruction, where countries maintain nuclear toolboxes to discourage attacks by appealing devastating retaliation. ElBaradei recommends that this technique is neither sustainable nor safe, provided the catastrophic humanitarian and ecological repercussions any nuclear dispute would entail.

ElBaradei proposes establishing a "different system of security" that does not rely on nuclear deterrence. This might involve strengthening worldwide organizations that promote discussion and conflict resolution, boosting conventional arms control, and focusing on diplomatic efforts over military might. By fostering worldwide cooperation and trust, nations might feel less likely to resort to nuclear posturing and more motivated to pursue disarmament.

Moreover, ElBaradei's call lines up with wider movements promoting for nuclear disarmament, such as the Treaty on the Prohibition of Nuclear Weapons, which intends to develop a legally binding course towards overall removal of nuclear weapons. The underlying principle is that worldwide security must not be based upon the hazard of annihilation however on collective efforts to deal with origin of dispute, such as economic inequality, political instability, and resource competition.

In summary, ElBaradei is urging a paradigm shift in how nations view and enact their security methods. By moving towards systems that do not depend upon nuclear arms, the international community can pave the way for a more stable and peaceful world.
