I remember back in 1992 when the US and Israel were accusing Iran of building Nuclear weapons and claiming that they would have a bomb ready within 3 years.
1995 came and nothing.
Since then, every year we hear the same story that they will have a nuclear bomb within 3 years. It has been 20 years and they are still saying it will be 3 years away.
To me, there is no credibility in the US and Israel's claim and almost seems certain that they are fabricating a false story (have been for decades) to justify an attack on Iran.
