Iranian nuclear threat

Time is ticking away on the Iranian march to producing nuclear weapons.
Israel has dropped the ball on lobbying the world to increase pressure and real sanctions that will force Iran to stop its dangerous path.
Israel can not allow a nuclear armed Iran.
So there are 3 choices.
1. Increase the pressure on the world to stop the Iranians once and for all.
2. Attack the nuclear plants like we did in Iraq and more recently in Syria.
3. Wait for the Iranians to develop nuclear weapons and start a nuclear arms race in the Middle East with Saudia Arabia, then Egypt, and others to follow.
Then one country or terrorists with access to the weapons will use one and use it on Israel with unimagineable casualties, the second and final holocaust.
I recommend the first option.
