The attack to Iran was not feasible in other aspects too. It is like this that Iran decide to attack US! It cannot . Dagan and Ashknazi if could not understand this, there was no reason they claim they understand any thing. They did the right job for every one Look your size. Honestly just putting on fire your forest will put the whole country in danger. Iran knew that it can survive a war. The people who governed that time Iran were millitary people who were disasterous for people inside Iran, but they were nough rational to calculate the games. They calculated that if sanction of Iran happens, US and Euroupe will fall into stagnation. They thought that US and Euroupean politicians are enough wise to not do it but they were not.As a starting point the Iranians inflamed the second Lebanon war to say what they will do. Israil and US got their answer. Then US moved to direct attack that oil price increased even in the decision level. 50 percent of the world oil production was in danger even in that time. Iran did not have any solution. Interaction is the bad option but more agressive options are indeed worst.
