“Why Only 9 Countries Have Nuclear Weapons? Full Details on Global Nuclear Power & Failed US-Iran Talks”

 “From Nuclear Non-Proliferation Treaty rules to global tensions — here’s why most countries don’t have nuclear bombs.”

New Delhi: Crucial peace talks between the United States and Iran, hosted by Pakistan, have ended without any agreement.

Speaking on Sunday, U.S. Vice President JD Vance said, “Despite several efforts, we were unable to bridge the differences between the two countries.”

However, he appreciated Pakistan’s role in facilitating the talks, along with the efforts of Prime Minister Shehbaz Sharif and Army Chief Asim Munir.

This was the first direct dialogue between the two nations since the Iranian Revolution in 1979, and its failure raises concerns about global stability.

💣 The ‘Exclusive Club’ of Nuclear Nations

Currently, only 9 countries in the world possess nuclear weapons:

United States

Russia

United Kingdom

France

China

India

Pakistan

North Korea

Israel

According to estimates, there are around 12,121 nuclear warheads globally, with nearly 90% held by the United States and Russia.

Russia has about 5,580 warheads, while the United States has around 5,044.

❓ Why Don’t Other Countries Have Nuclear Weapons?

The main reason is the Nuclear Non-Proliferation Treaty (NPT), signed in 1968.

Over 190 countries have joined this treaty.

It prevents new countries from developing nuclear weapons.

⚖️ Monopoly of Five Nations

Under NPT rules, only five countries that tested nuclear weapons before 1967 are legally allowed to possess them:

United States

Russia

United Kingdom

China

France

All other countries, even if technologically capable, would violate international law by building nuclear bombs.

🛡️ How Are Non-Nuclear Countries Protected?

Countries without nuclear weapons rely on protection from allied nuclear nations under the concept of a “nuclear umbrella.”

For example:

Japan and South Korea are protected by the United States.

🇮🇳🇵🇰 How Did India and Pakistan Get Nuclear Weapons?

Even though the NPT restricts nuclear weapons, both:

India

Pakistan

developed nuclear weapons because they never signed the treaty.

India argued the treaty was discriminatory and conducted nuclear tests for national security. Pakistan followed soon after.

🔍 Special Cases: Israel & North Korea

North Korea: Initially part of NPT, later withdrew and developed nuclear weapons.

Israel: Has never officially confirmed its nuclear weapons but is widely believed to possess them.

💸 Technical & Economic Challenges

Building nuclear weapons is extremely expensive and technologically complex.

Countries attempting secret development face strict global sanctions.

These sanctions can severely damage a nation’s economy.

For example, Iran has faced major economic pressure due to nuclear-related issues.

🌐 Conclusion

Because of strict international treaties, high costs, and global pressure, most countries prefer economic growth over nuclear weapons, keeping the number of nuclear-armed nations limited.
