Israel made airstrikes against Iraq when it was trying to develop nuclear weapons. Israel acted unilaterally. Openly, most of the world condemned Israel but internally even Iran had reasons to be grateful. And, as Wikileaks has revealed, Arabs countries who are terrified of a nuclear Iran are looking to Israel to act in its own self interest and thereby also protect them. Iraq never did get the bomb --thanks to Israel. If Israel strikes Iran one hopes it does so definitely. Iran WILL attempt to destroy Israel if it has the means to do so. Israel should attack. And such an attack may lead to much needed changes in the current Iranian regime.
