Michael Rubin: Bad Options on Iran, An Israeli strike won't suffice - '...In short, an Israeli strike might buy time, but it would not buy enough time. The Islamic Republic would arise from any attack with greater lethality than before. Any attack would be a huge gamble, albeit one that Israeli leaders are likely to take given the inability of the P5+1 to raise the cost of Iranian defiance to the point that the supreme leader, to paraphrase Khomeini's statement on ending the Iran-Iraq War, drinks his chalice of poison and agrees to step back from the brink. Alas, because the Western world does not share Israel's threat perception, it is neither likely to force upon the Islamic Republic the degree of coercion necessary to achieve a change of regime behavior, nor is it willing to lay the groundwork — through support for independent trade unions, independent civil society, and democratization — to assist Iranians seeking fundamental change in the nature of their regime. This will leave Israel with no choice but to act, setting off a cascade of events that will ultimately force the decisions that Obama ignores now.'
