The best means for the Iranians to prevent American aggression against Iran is to call international attention to America's threats of an aggressive attack on Iran. Consider that a person in a crowd can thwart a thief by pointing at him and shouting, "Stop Thief!" What is the crook going do then, steal in front of everyone?
If Iran loudly protests that the US is about to attack, and provides the evidence of a long standing policy and campaign by Israel to provoke the US to attack Iran, it will shine a spotlight on US aggression and deter it.
