Not only does Iran not wish to destroy Israel, it is also unwilling to allow Hezbollah to successfully do so either. If it wanted to destroy Israel, Israel wouldn’t have any AD after the last strike.
Will the balance of power change a few decades from now? Maybe, who knows, but for now Iran is in a tough spot.
But please feel free to provide a trustworthy news source backing your claim.
It seems to me like it's should be extremely easy to distinguish the two, there's more than enough earthquake data - and that fact that there is no such report says it all. For starters i'd even take an amateur analysis, but just some dude on twitter saying "there was seismic activity - must be a nuclear test" - nah.
