By Paul Krugman – The New York Times.

Betsy DeVos, whom Donald Trump has nominated as education secretary, doesn’t know basic education terms, doesn’t know about federal statutes governing special education, but thinks school officials should carry guns to defend against grizzly bears.

Monica Crowley, selected as deputy national security adviser, withdrew after it was revealed that much of her past writing was plagiarized. Many other national security positions remain unfilled, and it’s unclear how much if any of the briefing materials prepared by the outgoing administration have even been read.

Meanwhile Rex Tillerson, selected as secretary of state, casually declared that America would block Chinese access to bases in the South China Sea, apparently unaware that he was in effect threatening to go to war if China called his bluff.

Do you see a pattern here?

It was obvious to anyone paying attention that the incoming administration would be blatantly corrupt. But would it at least be efficient in its corruption?

Many Trump voters certainly thought they were choosing a smart businessman who would get things done. And even those who knew better may have hoped that the president-elect, his ego finally sated, would settle down to running the country — or at least delegate the boring business of governing America to people actually capable of doing the job.

So the typical Trump nominee, in everything from economics to diplomacy to national security, is ethically challenged, ignorant about the area of policy he or she is supposed to manage and deeply incurious. Some, like Michael Flynn, Mr. Trump’s choice as national security adviser, are even as addicted as their boss to internet conspiracy theories. This isn’t a team that will compensate for the commander in chief’s weaknesses; on the contrary, it’s a team that will amplify them.

Why does this matter? If you want a model for how the Trump-Putin administration is likely to function (or malfunction), it’s helpful to recall what happened during the Bush-Cheney years.

People tend to forget the extent to which the last Republican administration was also characterized by cronyism, the appointment of unqualified but well-connected people to key positions. It wasn’t as extreme as what we’re seeing now, but it was striking at the time. Remember “Brownie, you’re doing a heck of a job”? And it caused very real damage.

In particular, if you want some notion of what Trump governance is likely to look like, consider the botched occupation of Iraq. People who knew anything about nation-building weren’t wanted; party loyalists — and corporate profiteers — took their place. There’s even a little-known connection: Betsy DeVos’s brother, Erik Prince, founded Blackwater, the mercenary outfit that, among other things, helped destabilize Iraq by firing into a crowd of civilians.

Now the conditions that prevailed in Iraq — blind ideology, contempt for expertise, effective absence of any enforcement of ethics rules — have come to America, but in a far more acute form.

And what will happen when we face a crisis? Remember, Katrina was the event that finally revealed the costs of Bush-era cronyism to all.

Crises of some kind are bound to occur on any president’s watch. They appear especially likely given the crew that’s coming in and their allies in Congress: Given the stated priorities of the people about to take charge, we could very well see collapsing health care, a trade war and a military standoff with China just in the next year.

Real crises need real solutions. They can’t be resolved with a killer tweet, or by having your friends in the F.B.I. or the Kremlin feed the media stories that take your problems off the front page. What the situation demands are knowledgeable, levelheaded people in positions of authority.

But as far as we know, almost no people meeting that description will be in the new administration, except possibly the nominee for defense secretary — whose nickname just happens to be “Mad Dog.”

So there you have it: an administration unprecedented in its corruption, but also completely unprepared to govern. It’s going to be terrific, let me tell you.
