As of today, no country is known to have an Enhanced Radiation Weapon ("neutron bomb") in their active stockpile.
"Enhanced radiation" weapons, including the 'neutron bomb', have been stricken from the US inventory and are (probably) no longer a part of strategic planning.
No country is known to currently have neutron bombs. The concept was developed in the US in the early 1960s (and some testing along those lines was done by, at least, the US and France in the mid-1960s), and France actually tested a full neutron bomb in 1980.
Countries use nuclear bombs to pronounce dominance to the world and show that they are not to be messed with. They are also a quick, extremely hard blow that kill many and can end conflict extremely fast, like in WWII the United States dropped two bombs on Japan and very soon afterwards, Japan surrendered because the fear of more bombs had weakoned civilian morale and Japan could not take another hit like that.
Only the five permanent United Nations Security Council members - the United States, Russia, Britain, France and China - are known to possess hydrogen bombs.
nukes are not "bad for countries" but they have devistating side affects, for example: the cities of nagisaki and hiroshima are still highly radiated due to the original atomic bombs which were droped there.

Countries want them, countries make the laws.
Atomic bombs were not used anywhere in Europe in WW2. The only country that atomic bombs were dropped on in any war is Japan.
There are several processes that happen in atomic bombs, the main ones are:Fission bombs - hydrodynamics, neutron chain reaction, fission.Fusion bombs - hydrodynamics, radiation transport, thermonuclear fusion, fission.Many other secondary processes occur also.

Benefits: You can take out any living creatures without destroying as much buildings. Harmful effect(s): Neutron bombs can leave an area radioactive for days and disrupt electronics.
There are 8 countries with official ownership and control of atomic bombs: The US, Russia, UK, France, China, India, Pakistan and North Korea. There are 5 countries storing atomic bombs, but with ultimate custody for the bombs belonging to the US: Belgium, Germany, Italy, The Netherlands and Turkey. Israel is also believed to have atomic bombs. And Iran,possibly.

James Chadwick discovered the neutron in 1932. Leo Szilard got the idea of the neutron chain reaction as a means of releasing the energy of the atom in 1933 and filed a patent on this process in 1934 (the patent was granted in 1936 and promptly classified by the British Admiralty to prevent Germany from seeing it). However the breakthrough that made atomic bombs possible was the discovery of nuclear fission of uranium in 1939 by a joint German and Swedish team.
