Israel is the strongest country in the region, the only country in the region with Nukes, and Bibi is alive and well. Bibi is a very strong leader of Israel and while he will eventually be replaced (by an even more Hawkish leader). The idea of Israel threatening to Nuke Iran is not new and it was mentioned a few weeks ago. Not the first time Israel indicated this, not the last time.
cheers.
I am not sure if Bibi is in fact alive and well. I won't place a bet on it, but Israeli twitter is full of panic and alarm that he hasn't been seen in 6 days, 7 now? Guess we will see. But no Netanyahu, no nuclear codes. No Samson option. No total annihilation of Iran.
Threats given to the public are different than threats passed on between heads of state and through intelligence.
You over estimate Israel and underestimate a nation filled with people ready to die for their cause. Iran has virtually no lose condition outside of total destruction and genocide. Western powers on the other hand only need be attacked economically and structurally for the cracks to begin to show. Another thing. Iran is not in this alone.
