I see no reason that Iran couldn't do it, they have had longer than the typically required 4 years of nuclear infrastructure building time.
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.
I don't believe that Iran should have nuclear power because they threaten to bomb the USA if they do get nuclear power.
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.
Doubtful.
