That's all a bunch of baloney as far as I'm concerned. All that cyber-warfare, scientist-murdering, sanctions / Israeli airstrike threatening only encourages Iran to put more efforts into developing nuclear weaponry.
Me? I think the West should stop thinking about Iran's nuclear program as the big issue and start thinking about Iran's regime as the problem. Iran's goals of becoming a nuclear superpower ain't gonna fade away after a successful airstrike. Neither is Iran gonna become any less of an intolerant theocratic state. Wanna see changes? Gotta do it the hard way.
Unfortunately, this is NOT something world leaders like to admit, especially after Iraq and Afghanistan.
