The problem is that there are several reports of the IAEA, which are less than a decade old and tend to be quite factual saying that Iran has been effective developing the technologies required for a missile launched nuclear weapon. Please note "missile launched", which is much more difficult than other ways of delivering.

If Iran is close to the objective or not close to the objective is relatively irrelevant - what does matter is that they have been playing cat and mouse and eventually may reach their goal.

Such a goal is unnacceptable for Israel, the US and to others  - again not today, not in a week, not in a year. Build a new nuclear programme, keep calling for the destruction of Israel and you will get a war.
