Last night Iran wounded 63 (seven who required major, urgent surgeries.) and one dead because Iran happily fired missiles randomly across the middle east and hit random civilians in an airport terminal which this site would be screaming about if Israel/the USA did.
If Iran were to use a nuke it could easily start a chain reaction. Iran CURRENTLY has a billboard with a date for the erasure of Israel. They have a countdown clock. This is nothing like Hiroshima or Nagaski. Iran is targeting a country with over half the population of one ethnicity in the entire world. The 4.6million in greater Tel Aviv make up over 25% of all Jewish people in the entire world.
Iran's moderates in government pushed students off roofs to their deaths. That is the moderate Islamic Republic position and are not people that should have access to nuclear weapons.
