The article correctly indentifies problems of dealing with Iran: there is no diplomatic or economic sanctions solution to the problem.

After what Iran has already said about Israel and the Holocaust, no additional justification for such Israel's position is necessary. This approach will instantly make Iran everyone else's problem, especially its today's allies: who will want to invest in the country which could be destroyed in an instant because of its own stupidity.
