&gt;How else are Brazil, South Korea, Indonesia etc... able to protect themselves against nuclear states?<p>The US is a nuclear state, and the only state to have ever used nuclear weapons in warfare. Who&#x27;s going to defend the world against the threat of American nuclear aggression? Will the world really be safer when only the US has nuclear weapons?<p>Reducing nuclear proliferation is a noble endeavor, but the United States should not be the one leading the effort towards it as long as it has no intentions of dismantling its own arsenal.<p>The world would be safer without nuclear weapons, but as long as the US remains an aggressive, nuclear military power that kidnaps, tortures and murders civilians in other countries with impunity, undermines their governments at will, supports terrorist groups and wages war on fabricated evidence, a nuclear-free world will remain impossible.
