In that regard, apparent disagreement on specifics masked a deeper consensus consisting of three elements:
* That ISIS represents something akin to an existential threat to the United States, the latest in a long line going back to the totalitarian ideologies of the last century; fascism and communism may be gone, but danger is ever present.
* That if the United States doesn't claim ownership of the problem of Iraq, the prospects of "solving" it are nil; action or inaction by Washington alone, that is, determines the fate of the planet.
* That the exercise of leadership implies, and indeed requires, employing armed might; without a willingness to loose military power, global leadership is inconceivable.
In a fundamental respect, the purpose of the national security establishment, including the establishment media, is to shield that tripartite consensus from critical examination. This requires narrowing the aperture of analysis so as to exclude anything apart from the here-and-now. The discussion in which I participated provided a vehicle for doing just that. It was an exercise aimed at fostering collective amnesia.
So what the former secretary of defense, think tank CEO, and retired general chose not to say in fretting about ISIS is as revealing as what they did say. Here are some of the things they chose to overlook:
* ISIS would not exist were it not for the folly of the United States in invading -- and breaking -- Iraq in the first place; we created the vacuum that ISIS is now attempting to fill.
* U.S. military efforts to pacify occupied Iraq from 2003 to 2011 succeeded only in creating a decent interval for the United States to withdraw without having to admit to outright defeat; in no sense did "our" Iraq War end in anything remotely approximating victory, despite the already forgotten loss of thousands of American lives and the expenditure of trillions of dollars.
* For more than a decade and at very considerable expense, the United States has been attempting to create an Iraqi government that governs and an Iraqi army that fights; the results of those efforts speak for themselves: they have failed abysmally.
Now, these are facts. Acknowledging them might suggest a further conclusion: that anyone proposing ways for Washington to put things right in Iraq ought to display a certain sense of humility. The implications of those facts -- behind which lies a policy failure of epic proportions -- might even provide the basis for an interesting discussion on national television. But that would assume a willingness to engage in serious self-reflection. This, the culture of Washington does not encourage, especially on matters related to basic national security policy.
My own contribution to the televised debate was modest and ineffectual. Toward the end, the moderator offered me a chance to redeem myself. What, she asked, did I think about Panetta's tribute to the indispensability of American leadership?
A fat pitch that I should have hit it out of the park. Instead, I fouled it off. What I should have said was this: leadership ought to mean something other than simply repeating and compounding past mistakes. It should require more than clinging to policies that have manifestly failed. To remain willfully blind to those failures is not leadership, it's madness.
Not that it would have mattered if I had. When it comes to Iraq, we're already halfway back down Alice's rabbit hole.
