Actually this is false most of the Cold War era nuclear weapons have been destroyed.
Let's hope we never find out. The Soviet Union was shown not to have as many weapons as they boasted after the fall of communism. It is reasonable to assume the current weapons stocks of Russia are not as deep as those of the United States, who pours money into such things.Tests on nuclear weapons have been banned for some time now both below, and above ground. So there's not much room for improvement in terms of making a more potent bomb or warhead.
The US was concerned and saw the Soviet acquisition of nuclear power as a potential threat to its security. This led to an increase in military spending and the development of their own nuclear weapons program during the Cold War.
The Russian nuclear lab you might be referring to is likely the Mayak Production Association, also known as Chelyabinsk-40 or Chelyabinsk-65. It was involved in the production of plutonium for nuclear weapons during the Soviet era and has a history of nuclear accidents and environmental contamination.
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.
The development of the hydrogen bomb greatly escalated the arms race between the United States and the Soviet Union during the Cold War. It increased tensions and spurred both nations to further expand their nuclear arsenals. The creation of this more powerful and destructive weapon deepened the sense of mutual distrust and fear between the two superpowers.
The Soviet Union had begun to install nuclear weapons in Cuba.
Reduce Nuclear Weapons, people! I HAVE FURY!
Yes
Because the US already had offensive nuclear weapons in Turkey. They saw it as "balancing" things.
Reduce nuclear weapons

Soviet Union 1949
It marked the first attempt to restrict US and Soviet nuclear weapons.The SALT-1 Strategic Arms Limitation Treaty stopped the growth in US/Soviet intercontinental-range nuclear weapons arsenals. It was signed at Moscow May 26, 1972. It was approved by U.S. President September 30, 1972. The leaders were U.S. President Richard M. Nixon and Soviet leader Leonid Brezhnev.
If the island is Cuba, 1962
It showed that the USSR had nuclear weapons.
Russia, of course.
