From The Gloria Center, April 21, 2009, by Barry Rubin [my emphasis added - SL]:
Why did Iranian President Mahmoud Ahmadinejad, with the full backing of Iran's regime, behave as he did at the Durban-2 conference? One reason, of course, is that he believed every word he said ...Ideology was central.
...The second factor that should be remembered is that of miscalculation. A leader, particularly if reckless and overconfident, will take an action he thinks is in his interest but turns out to be a disaster. The best internal Middle East examples are those of Egyptian President Gamal Abdel Nasser provoking the crisis that led to the 1967 war and Iraqi President Saddam Hussein's invasion of Kuwait in 1990.
...For Ahmadinejad ...ideology and miscalculation are major factors. They will continue to be major factors if Iran gets nuclear weapon.
But of course, as with Nasser and Saddam Hussein, there are shorter-run calculations. Three are important:
Domestic popularity. This is always a basic factor with Middle Eastern radical regimes. Not all Iranians will support Ahmadinejad and many hate the regime. But among the 20 percent hardcore and perhaps 50 percent total who can be mobilized, they may cheer Ahmadinejad. Iran is strong, its enemies are weak, and its leadership is courageous. America, the Jews, and the West are satanic. Rally to the Islamic regime!
Regional popularity. Iran's regime is seeking to be leader of the Muslim world and the leading power in the Middle East. But in doing so it has two very big problems: Iran is mostly Shia Muslim; most Muslims (especially Arabs) are Sunni Muslims. Iran is mostly ethnically Persian; Arabs are Arab. How to overcome these barriers? Iran already has Arab and largely Sunni allies--Syria, Hamas, Hizballah-but that's not enough. So by becoming the leader against America, the West, and Israel, Iran hopes to override these problems. Who cares if we are Persian and Shia, Ahmadinejad says, we are the true Muslims doing what your governments aren't doing.
Global popularity. While this is a miscalculation, Ahmadinejad and other regime leaders believe that this kind of behavior can make them popular throughout the world. This includes not only Muslim-majority countries but also the Third World and even the West. In a recent interview with Der Spiegel magazine [see source below] Ahmadinejad said that he believed most Germans also hated Israel and wanted to see it wiped out. Certainly, there is reason for him to believe such things.
Some better-informed regime leaders view Ahmadinejad as a disaster. The problem is that the top leadership is backing him, and thus his words and actions do represent the regime. The June elections will almost certainly return him to office for more years, years during which Iran will get nuclear weapons.
There's one other extremely important point on which Ahmadinejad is misunderstood. It is true that he does not control the government. The most powerful man in Iran remains the supreme guide, Ali Khamenei. But Ahmadinejad, allied with powerful current and former Islamic Revolutionary Guard Corps officers, is building his own apparatus. In the future, he could well emerge as the uncontested leader of Iran. For the moment, though, it is enough that he has the regime's backing.
Ahmadinejad and other Iranian leaders-though not all-believe the West is weak and cannot respond to their aggression. They are not, as sympathizers portray them in the West, trembling people motivated by fear of external attack. Clearly, Iran has legitimate security concerns. But the real threats are heightened by their own behavior. If they were in fact so frightened they could change policy and reduce the threat. Some regime leaders, though not those in control right now, advocate just such a policy. Unfortunately, the West hasn't helped them enough by making that threat more credible through denunciations and effective sanctions.
So here's the bottom line: by failing to oppose Iran more effectively, the West is unintentionally encouraging it to be more extremist and dangerous. By failing to help relatively moderate Arab regimes, the West is making them more susceptible to having to appease Iran. By pressuring and criticizing Israel, the West is encouraging Iran's regime to believe it can be destroyed.
Not a pretty picture. But neither is that of the would-be fuehrer being an honored guest at UN meetings. No wonder Ahmadinejad and his backers believe that theirs is a winning bet.
