Do you think that Iran will sit there with its arms crossed as we destroy their economy? They will retaliate. Iran will close the Straights of Hormuz, bomb every oil installation in the Persian Gulf, get the Shias in Iraq to invade the Green Zone and attact American where ever they are. Make trouble in Afganistan. The Iranians/Persians will fight to the death because they have been preparing for this. By killing Iranian scientists, you are playing with matches and gasoline. Remember how the WWI got started. Read history.
