no, you will know if they do
No they did not yet
At this time:in a bomb, very cheapin a reactor, not yet possible
Iran wants to be big man in the neighborhood. Not yet.___________________________________________Iran never declared that it needs a nuclear bomb and never tried to have it. Iran; as declared; is building up a peaceful nuclear power program.
Nuclear bombs before the 60s were referred to as atom bombs, because the term Nuclear hadn't been discover yet. Nuclear bombs today, are generally Hydrogen bombs, or fusion bombs. They are significantly more powerful, able to places about the size of Rhode Island. Atom bombs,which were mostly uranium and plutonium, lack the destructive power of Nuclear or Fusion bombs.
both r useless Sometimes "atom" bomb is also used to describe a hydrogen bomb. Strictly, historically speaking, the atom bomb works via the energy released when a heavy atom nucleus such as uranium is split (called nuclear fission). This is also the energy source for nuclear power stations. A hydrogen bomb works via the energy released on fusing (called nuclear fusion) two light atoms (such as hydrogen) together - the huge pressure needed is derived from an atom bomb. This situation arises because the atoms towards in the middle of the periodic table are more stable, than those nearer the ends. A lot of electricity is derived nowadays from nuclear fission (nuclear power stations) but no significant power has yet been derived from nuclear fusion, though a lot of work is being done on it.
Because Japan had not surrendered yet. There was also a danger that Japan would surrender to Russia as opposed to the US.
We don't know much about fusion as it is still very experimental. It will not produce the dangerous fission products that fission does, but it may have other dangers unknown as yet. Nuclear fusion has more destructive potential than fission. Fusion is the principle powering the H-bomb developed in the Cold War. Just to put the power of a Fusion bomb in perspective, it is detonated by a fission bomb half the size of the one dropped on Japan. THAT'S JUST THE DETONATOR.
First, when those Island were invaded, the nuclear bomb was not ready yet. Second, it took a place in the main island for the bomb to be taken seriously.
It is possible, and we have done exactly that on many occasions, with tests of thehydrogen bomb and other thermonuclear weapons.What we have not yet accomplished is to develop a way to do it in a controlled, less messy,more elegant way.
not yet
In a controlled fusion reaction, a process of nuclear fusion occurs, but it is controlled, so that it does not grow uncontrollably, to become, for example, a thermonuclear bomb. Note: This has not been accomplished yet.
