We need to be careful about attacking Iran. Most wars have unexpected consequences, but with Iran they are more severe. - One oil tanker sunk in the Straits of Hormuz could close the entire waterway. Most of the world's oil travels through there. - What if Iran launches a series of devastating terrorist attacks on American soil? Hundreds or thousands may die. America would be obligated to launch a fullscale invastion of Iran. - What if Russia or Turkey enter the war on Iran's side? - What if Israel is attacked by all Arab nations simultaneously? We would be obligated to fight on Israel's side against the Arabs. What happens to the world's oil supply then? There are many reasons to resist fear mongering and think this through.
