Obama is by far the most left-wing president the US has ever had, and his thinking conforms to a certain pattern. In broad strokes, I perceive those on the left as believing that problems can be solved with good will, by reaching out, and by promoting dialogue. They believe that confrontation is counter-productive (if not just plain wrong), and they are more ready to be appeasing. While those on the right see the reality of evil and believe that what is required sometimes is to boldly identify it and then undertake a strong confrontation with it (with the conviction that to fail to do so would be wrong).
Obama's efforts with regard to Iran have been a disaster, because he has drawn on his ideology in attempting to solve the problem of Iranian intransigence. Netanyahu is correct when he says that efforts with Iran won't succeed unless Iran knows there is a credible threat of military action. Obama declines to play it this way.
Similarly he has opted to send an ambassador to Syria, claiming that having a US spokesman on the scene will allow for a better exchange of ideas, present opportunities for increasing US influence, etc. etc. But, in reality, he is effectively rewarding Syria for hostile and belligerent actions, and giving it the wrong message. Syria should have been isolated to the maximum.
As a result of the way Obama plays it, US deterrence power in the Middle East has dropped. This encourages boldness on the part of terrorist groups, and terrorist-supporting states. It is counterproductive to peace. And this, I believe, Obama does not understand. I believe he is badly deluded.
Do I think Obama is a closet jihadist who secretly desires the hegemony of Iran or the emergence of a new caliphate? Do I think that he sees it as a victory, that terrorists are feeling stronger? I most certainly do not.
What I do believe is that Obama is an internationalist, who curtails American power deliberately. But in the course of curtailing that power, I strongly suspect that he has generated some unintended results.
Nobody could say it any better.
