"That is why I am going to the UN's General Assembly to tell the nations of the world in a clear voice the truth about the terror regime of Iran which represents the greatest threat to world peace".
Meanwhile, efforts to arrange a meeting between Netanyahu and US President Barack Obama continue. Relations between the two are tense over disagreements on the timetable for a possible military operation in Iran.
The prime minister is planning to speak out against Iran's nuclear program in a particularly poignant speech in order to increase pressure on the international community in the hopes it will work to prevent Iran from obtaining a nuclear weapon.
Meanwhile, senior state officials insinuated that the US will back any decision Israel will make on a strike in Iran ruling out a possible diplomatic crisis between the two nations.
"We are not worried about a crisis with the US, no matter what we decide," a state official said.
Netanyahu is scheduled to depart for New York immediately after Yom Kippur and will return to Israel three days later.
