• Nine countries officially possess nuclear weapons, with two others unofficially, while South Africa is the only nation to voluntarily dismantle its arsenal.
• The Nuclear Non-Proliferation Treaty (NPT) aims to prevent new countries from acquiring nuclear weapons and encourages existing powers to disarm.
• America's policy, supported by the P5 nations, is to prevent new nuclear powers, leading to strict measures against countries like North Korea and Iran.
• Israel is believed to possess nuclear weapons, a fact America does not challenge, while Iran's pursuit of nuclear capability raises concerns for regional stability and Israel's security.
• Building a nuclear bomb is complex, requiring immense financial investment, advanced uranium enrichment, and miniaturization technology, making it a significant challenge for any nation.
