Iran nuclear weapons: How close is Iran to developing a nuclear bomb?

Some diplomats and nuclear experts have said the starting point of one year is conservative and Iran would need longer.

But David Albright, a former UN weapons inspector, estimated in November 2020 that Iran’s breakout time could be “as short as 3.5 months”.

If Iran accumulated enough enriched uranium, it would still need to assemble a bomb, which is no small feat.

But stockpiling enough fissile material is widely seen as the biggest hurdle in producing a nuclear weapon.
