Caroline Glick has another good essay in the Jerusalem Post comparing Clinton and Obama. My favorite passage is the following:
THERE ARE two reasons that a deterrence model will be as ineffective in curbing Iranian aggression as Obama's appeasement model. First, as last week's 25th anniversary of the Iranian-sponsored bombing of the US embassy in Beirut recalled, Iran has been attacking the US and its allies both directly and through proxies since 1979. To date, not only has the US failed to deter such attacks, it has never made Iran pay a price for them. With this abysmal track record against a non-nuclear Iran, it is hard to see how the US can threaten a nuclear-armed Iran with sufficient credibility to make a deterrence-based strategy successful.
The second reason that basing US policy towards Iran on a deterrence model will likely fail is because Iran's leadership has made clear that is not necessarily concerned about the survivability of Iran. From Ayatollah Khomeini to Ayatollah Khamenei to Ali Rafsanjani to Mahmoud Ahmadinejad, Iran's leadership has made clear that they are not Iranian patriots but global Islamic revolutionaries. Given their millenarian, apocalyptic view of their country's purpose in world affairs, there is good reason to believe that a strategy based on some form of mutually assured destruction would have only marginal impact on Iran's decision-makers.[emphasis added]
