I think Iran has been walking the tightrope and thoroughly enjoying the stress and anxiety it causes Israel, who can't prove Iran has one or not.
 
Everytime Israel claims Iran has one, or is getting close, Iran says,
 
"But No Mr. IAEA, I don't even know verr is it!"
 
Obviously Iran enjoys torturing Israel by slyly hinting it can get one. I think it has been a huge bluff to make everyone think their hand is strong.
 
Which is smart, because if now as Israel attacks Iran, it turns out Iran doesn't have one, or wasn't close to getting one, Israel looks bad.
 
But Iran must know that if it comes out that they are close, or have one, they will look like the terrorist everyone calls them.
 
But both Israel and Iran are ultimately stupid countries. And not above making huge strategic mistakes that makes both look even more stupid.
 
So Israel will either be proven stupid/wrong if Iran doesn't end up being close or having nukes.
 
Or Iran will end up being shown as the terrorist they are, if Israel proves they were close or have one.
 
Trump will once again be too busy stealing money and taking bribes to realize the opportunity to fix past US mistakes in Iran properly for once, by taking out Khamenei, and putting Reza Pahlavi back with financial and security support, in a limited (1 year?) task of rooting out the Islamic Republic thugs, and installing a democratic government, and then stepping aside as a ceremonial monarch like Queen Elizabeth.
 
One action fixes everything. 
 
No action is yet another strategic mistake by the US. Israel and Iran are bot simultaneously smart and stupid for creating the conditions everyone in both countries now has no choice but to suffer.
