Stephen M. Walt in Foreign Policy:
Over the past few weeks, proponents of the nuclear deal with Iran — from President Barack Obama on down — have marshaled a powerful attack on some of the deal’s most prominent opponents. Specifically, they’ve been pointing out an indisputable fact: Many of the individuals and organizations that are most actively lobbying and speaking out against the deal helped dream up the idea of invading Iraq or worked hard to convince Congress and the American people to go along with the idea. The logic of the pro-deal camp is simple: Given that the opponents were so catastrophically wrong about the Iraq War, no one should listen to their advice today.
I agree with this basic argument, of course, but opponents of the deal do have one line of defense against the “Wrong on Iraq, Wrong on Iran” meme. It is possible someone could have been dead wrong about the wisdom of invading Iraq in 2003, but nonetheless be correct to oppose the nuclear deal with Iran today. None of us is infallible, and it is at least conceivable that Bill Kristol, Elliott Abrams, James Woolsey, Fred Hiatt, Max Boot, et al. could have blown it big-time in 2002 — but be absolutely right this time around.
Conceivable, I suppose, but highly unlikely. Why? Because their views in 2002 aren’t independent from the views they’re expressing today. On the contrary, their earlier support for the Iraq War and their opposition to the Iran deal stem from the basic neoconservative worldview that informs their entire approach to foreign policy.
