IAEA chief Rafael Grossi says Iran is close to acquiring a nuclear bomb before diplomatic talks resume.

Iran enriches uranium up to 60% purity after US withdrawal from the 2015 nuclear deal.

A detailed list of nuclear-armed nations and key treaties like NPT and New START explained.
In a concerning development, Rafael Grossi, the head of the International Atomic Energy Agency (IAEA), has made a startling declaration that Iran is "not far" from acquiring nuclear weapons. This statement came just before Grossi’s arrival in Tehran for urgent talks with Iranian officials, including Foreign Minister Abbas Araghchi. Grossi’s remarks have raised alarm globally as they signal that Iran’s nuclear capabilities could soon align with those of other nuclear-armed states, potentially altering the balance of power in the Middle East and beyond.
Grossi emphasized the importance of cooperation with the IAEA to provide credible assurances regarding the peaceful nature of Iran’s nuclear program, especially at a time when diplomatic efforts are needed to avert further escalation. Iran has been enriching uranium to levels as high as 60 percent purity, a step close to weapons-grade material, which is typically 90 percent purity. This level of enrichment has intensified international concerns that Tehran is rapidly advancing its nuclear program, particularly after the United States withdrew from the Iran nuclear deal in 2018 under former President Donald Trump.
Iran's Nuclear Program:
Iran’s nuclear program has long been a subject of international scrutiny. The country’s decision to enrich uranium to near-weapon-grade levels follows the United States’ unilateral withdrawal from the Joint Comprehensive Plan of Action (JCPOA), the nuclear agreement negotiated between Iran and major world powers. Since then, Iran has steadily expanded its nuclear activities, raising fears that it could soon possess nuclear weapons, thus becoming the 10th nation globally to do so.
If Grossi’s warning proves true, Iran will join the ranks of nine other countries that currently possess nuclear weapons. These nations have long been the subject of global arms control efforts, particularly through frameworks like the Nuclear Non-Proliferation Treaty (NPT), which aims to prevent the further spread of nuclear weapons.
List of Nuclear-Armed Countries:
As of now, the following countries are recognized to possess nuclear weapons, with their estimated arsenals listed below:
-
Russia: 5,880 nuclear warheads
-
United States: 5,225 nuclear warheads
-
China: 600 nuclear warheads
-
France: 290 nuclear warheads
-
United Kingdom: 225 nuclear warheads
-
India: 172 nuclear warheads
-
Pakistan: 170 nuclear warheads
-
Israel: 90 nuclear warheads (Israel follows a policy of nuclear opacity and has never officially confirmed its nuclear arsenal)
-
North Korea: 50 nuclear warheads
While the United States and Russia possess the largest stockpiles of nuclear weapons, both countries have also made efforts to modernize their nuclear delivery systems under agreements like the New Strategic Arms Reduction Treaty (New START), which limits the number of deployed warheads and delivery vehicles. The treaty was signed on April 8, 2010, between the US and Russia and came into force on February 5, 2011.
The Nuclear Non-Proliferation Treaty (NPT):
The NPT, signed in 1968, was designed to prevent the spread of nuclear weapons and encourage peaceful uses of nuclear energy. The treaty has been signed by 191 countries, including the five permanent members of the United Nations Security Council—Russia, the United States, China, France, and the United Kingdom—who are also recognized nuclear-armed states. However, three major countries—India, Israel, and Pakistan—never signed the NPT and have developed their nuclear arsenals outside the treaty framework.
Despite the NPT's efforts, nuclear proliferation remains a significant global concern. The withdrawal of the US from the Iran nuclear deal and Iran’s subsequent steps towards enhancing its uranium enrichment capabilities underscore the challenges of maintaining non-proliferation norms in a rapidly changing geopolitical landscape.
Future Prospects and Global Impact:
The potential for Iran to develop nuclear weapons has significant implications for regional security, particularly in the Middle East, where several countries have expressed concerns about Tehran’s growing nuclear capabilities. These developments could lead to a renewed arms race in the region, as other nations may feel compelled to develop their own nuclear weapons in response.
The international community is closely watching the ongoing negotiations between Iran and the United States. These discussions, which are expected to continue in an indirect format, aim to find a diplomatic solution to prevent Iran from crossing the nuclear threshold. However, with tensions escalating and nuclear capabilities advancing, the situation remains precarious.
In conclusion, the possibility of Iran acquiring nuclear weapons adds a complex layer to the already volatile dynamics of global nuclear politics. As countries like the US, Russia, and China continue to modernize their nuclear arsenals, the threat of nuclear proliferation remains one of the most pressing issues in international security.
