There are two questions here.
Why does Iran need a nuclear bomb? -- Iran does not NEED a nuclear bomb. Iran WANTS a nuclear bomb since having a nuclear weapon would, in Iran's view, lessen the advantage that Israel has over its neighboring Islamic States. It would also be a symbol of Iranian power and a projection of Iranian influence and civilization.
When will Iran have a nuclear bomb? -- The timeline for Iran gaining a nuclear weapon is unclear. It is likely that Iran will have sufficient fissile material to make a bomb by late 2015 or early 2016. However, the Israeli Mossad has performed a number of operations aimed at delaying the creation of such a weapon.
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.
no
If you are asking which has the maximum danger, a hydrogen bomb is one type of nuclear bomb. In general, nuclear bombs can be fission (called atomic) or fusion (hydrogen) A fusion bomb is larger than an fission bomb, and actually uses a fission bomb to start the fusion reaction.
a nuclear one.
No, in terms of destruction the hydrogen bomb is the strongest, but if you mean killing the plutonium bomb is the one that does the most killing.
It was a atom bomb. The uranium one and it was called the "little boy".
It wasn't just one bomb.. It was a huge nuclear bombardment during the Great War with China.
one no, many yes
That is the big question. No one knows for sure.
The terms "atomic bomb" and "nuclear bomb" are general terms and can pretty much be used interchangeably. That said, there isn't any difference between them, and one is not more powerful than the other in that light.
No one. The first nuclear device was not tested until July of 1945, and the first bomb was not produced (not used) until later that month.
