If by states you mean countries:
If by states you mean US states, this is harder to answer as exact locations of many weapons is classified. However all states with ICBM bases have them, all states with nuclear missile submarine bases have them, all states with strategic bomber airbases have them, Texas has them as they are remanufactured just east of Amarillo, etc.
China is not a nuclear free zone. They have many nuclear weapons. Though China has a nuclear policy which states that they are not allowed to produce,fire, or give away these weapons.
Both Russia and the United States possess strong nuclear arsenals with similar destructive capabilities. The exact strength of each country's nuclear weapons is classified, but they both have the ability to cause immense damage and are considered two of the most powerful nuclear states in the world.
The countries known to have nuclear weapons are: United States Russia United Kingdom France China India Pakistan North Korea Israel Germany, Italy, Japan and South Africa have the capability of building nuclear weapons but have not done so. Canada once had nuclear weapons, but has dismantled its weapons and permanetly deacitvated its nuclear weapons program. So far it is the only country to do so.
"Nukes" is a colloquial term for nuclear weapons, which are explosive devices that derive their destructive power from nuclear reactions. These weapons can cause devastating damage and are considered weapons of mass destruction.
U.S. President Ronald Reagan and Soviet President Mikhail Gorbachev came within a hair's breadth of agreeing to phase out their stockpiles of nuclear weapons. General Zhu Chenghu of China's National Defense University, made some remarks that stirred an unusual uproar in the West and in the United States in particular. According to reports in the Western media, Gen. Zhu, in responding to questions in a briefing session on China's foreign and security policy with a delegation of foreign journalists based in Hong Kong, seemed to indicate that in a possible military conflict with the United States over Taiwan, Beijing would be no match for the United States in terms of conventional capability. Zhu thus suggested that China should perhaps be the first to use nuclear weapons to deter a possible U.S. intervention. Today, the United States is the only nuclear power that continues to deploy nuclear weapons outside its own territory. The approximately 480 nuclear bombs in Europe are intended for use in accordance with NATO nuclear strike plans, the report asserts, against targets in Russia or countries in the Middle East such as Iran and Syria. Israel has not confirmed that it has nuclear weapons and officially maintains that it will not be the first country to introduce nuclear weapons into the Middle East. Yet the existence of Israeli nuclear weapons is a "public secret" by now due to the declassification of large numbers of formerly highly classified US government documents which show that the United States by 1975 was convinced that Israel had nuclear weapons But as the questions says, there should no be nuclear weapons.
All of them have nuclear weapons cause they are the United States.
The United States does not give or sell nuclear weapons to any country. The United States has stationed nuclear weapons on the territory of many countries, but always retained full control of them.
China is not a nuclear free zone. They have many nuclear weapons. Though China has a nuclear policy which states that they are not allowed to produce,fire, or give away these weapons.
The United States of America was the country that developed the first nuclear weapons.
The first nuclear weapons were developed in the united States under the Manhattan Proyect which made the first nuclear bombs.
Many countries have nuclear weapons today including the United States. China, North Korea, South Korea, and Japan also have nuclear weapons.
Reduce Nuclear Weapons, people! I HAVE FURY!
In the most basic sense, proliferation of nuclear weapons is the spread of nuclear weapons and weapons usable technology in the world. In a much broader sense, it refers to the acquiring of capability to produce nuclear weapons, or weapons-grade nuclear material (high-enriched uranium, plutonium) by states previously not possessing them.
From 1945 until the late 1970s or early 1980s the United States always had the most nuclear weapons. After then the USSR/Russia has had the most nuclear weapons.
A nonnuclear state is a country that does not possess nuclear weapons and is not recognized as a nuclear-armed state under the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). These states may participate in international agreements to prevent the spread of nuclear weapons and promote disarmament. Nonnuclear states often advocate for nuclear disarmament and the peaceful use of nuclear energy.
The United States of America
According to my research the most weapons country is the United States currently owns 9,600 nuclear weapons, while Russia currently owns 16,800. But Russia actually always had more nuclear weapons than the United States.
