"If Israel attacks Iran, Israel will suffer greatly, but it will make interesting news each morning with my cup of tea." Sorry to disappoint you but the Israelies are about as afraid of the Iranians as the US is. An Iranian general just announced that Iran has 11,000 missiles that can be launched within a minute of being attacked on already identified targets. When Iran is attacked they will get their chance to show how much of what they have been saying is true over the past 2 years, regarding their armaments. Savour your tea Natallie, because if Iran retaliates against the US or Israel, you will likely witness the first 90 minute war in history. As you mentioned, the western nations are really uninterested in suffering casualties so the war will be over in less than a few dozen flashes should Iran flex its "might".
