The smallest nuclear bomb ever developed is the W54, which was used in the Davy Crockett nuclear weapon system by the United States. It had a yield of 10 to 20 tons of TNT equivalent.
Yes, nuclear bombs are real and have been developed and tested by several countries. These weapons derive their explosive power from nuclear reactions, which release enormous amounts of energy. The use of nuclear bombs is highly destructive and devastating, making them a major concern for global security.
Fusion reactors have not been developed and built yet because it is a complex and challenging process to control and sustain nuclear fusion reactions at a scale that is practical for energy production. Scientists are still working on overcoming technical and engineering obstacles to make fusion power a viable and reliable source of energy.
There is no record of a nuclear explosion occurring on November 6, 2010. If there had been a nuclear explosion, it would likely have been a significant event that would be widely documented.
Nuclear-powered aircraft were researched in the mid-20th century, but none were ever successfully developed or used. The main challenges included safety concerns, weight of the reactor, and potential radiation exposure to crew and passengers. The idea has largely been abandoned due to these challenges and the focus has shifted to other forms of propulsion for aircraft.
As far as I know nuclear weapons have never been traded between countries, so if a country has nuclear weapons it is due to their own science and technology, or to espionage activities to get the required knowledge. The other criterion is not to have signed up to the Non Proliferation Treaty, except for countries that had already developed weapons when the Treaty came into being.
It has not been developed enough to make this clear
Because nothing to safely hold the process in has been developed yet.
Yes, witness the many hundreds of nuclear power plants in the world today, most of which have operated entirely safely.
Not that they have ever admitted - and the popular sentiment in Japan has always been very ANTI-nuclear. However, with China becoming more aggressive, and with the nationalist Abe running the country, it's possible that they've developed them and not let anyone know. Certainly, Japan has the technology and resources to do so, and with the North Koreans threatening the use of nukes, it's entirely possible that both Japan and South Korea have their own nuclear arsenals.
The immediate effect was that Japan sued for peace. There is a movement underway to condemn the Americans (even in their own country) for the use of the nuclear weapon. Given the situation at the time, a new untried weapon would have been justified. There was no possible way to know what the consequences of nuclear weapons would be. Now, over 60 years later, nuclear energy has a history. Then, in World War 2, it was new, untried, and very likely could have failed. Sadly, war is just that...WAR. The objective is to win the war with as little human loss as possible. When new technology is developed, no one knows what the consequences will be in the future.
Nuclear power plants, submarines and aircraft carriers propelled by nuclear reactors. In the future, may be all sort of vehicles could have small and very protected nuclear reactors instead of today's fuel.

because is has not yet been vearyfied that nuclear fusion takes place
Using nuclear energy is possible, and in fact being done. It has been done since the 1940s. The first nuclear electric plant came on line some time after that, but I worked at one in the 1980s.
The answer depends on the degree of rounding and since that information has not been provided, it is not possible to answer the question.
Fission. Fusion has never been used on Earth, except for nuclear weapon tests.
Nobody. There have only been two nuclear weapons ever used in a time of war. Both were dropped on Japan at the end of WWII by the United States military. Many other countries have developed and tested their own nuclear weapons, but none have been used to kill.
