> The Iranian nuclear scientist in question was building a nuclear bomb to destroy Israel.

You can't just say that without tons of credible evidence to back it up.

Especially given Iran has no nuclear weapons while Israel does have them and refuses to sign any regulating treaty.

> In the U.S. our nuclear arsenal is a defensive weapon. So, not morally equivalent.

think you forgot the sarcasm tag. The U.S. is the ONLY country in history to have ever used nuclear weapons offensively.

The Iranians have followed the nuclear deal, the U.S. has pulled out and violated the agreement. If anything, it is the U.S. that has shown itself as the irrational player here.
