Israel is not at all able to launch any kind of 'independent' strike against Iran without the connivance of the US. The US would need to provide the miljet fuel, the specialist bombs required, overfly clearances, intel, and, above all, the support Israel needs to fend off retaliation by Iran directly and Hezbollah and Hamas indirectly. A strike against Iran will need to be more than just a strike against Iran's nuclear sites; it will need to have to bring Iran to its knees. There is only one way Israel can do that... The world doesn't want to go there. It would mean the end of Israel as well as Iran.
