The former Israeli military official I spoke with Sunday in Tel Aviv suggested three possible explanations for Netanyahu’s lack of action: 1) He is paralyzed and won’t act, no matter what he believes the threat to be; 2) He fears he would risk a serious rupture in his country’s alliance with the U.S. if he attacked Iran unilaterally; and 3) It’s all part of a game, one he has tacitly engineered with Obama.

I remain fairly confident that Netanyahu means it when he says that Israel would strike Iran to prevent it from going nuclear, but this third option is an interesting one, mainly because the game — a sustained Israeli bluff — would seem to be working so well.

[Obama and Netanyahu] have accomplished something extraordinary together over the past two years. The sanctions Obama has placed on Iran are some of the toughest ever placed on any country. Even some hardliners now believe that they just might force a change in Iran’s nuclear calculus. And how has Obama convinced the world that these sanctions are necessary? By pointing to Netanyahu and saying, “If you don’t cooperate with me on sanctions, this guy is going to blow up the Middle East.”

Obama’s good-cop routine is then aided immeasurably by the world’s willingness to believe that Netanyahu is the bad cop.
