An Israeli attack on Iran is likely to be a disaster for Israel and everybody knows this. The 2006 war was a disaster for Israel and it was a simple war directly on Israel's doorstep. Russia and China are both sponsors of Iran and may very well have contributed some surprises to the unsuspecting attacker. I hope we all get a chance to see what Israel can do.
