Protectionism: Krugman-Buiter Crash?

"Buy American" clause in the U.S. stimulus bill?

Willem Buiter wrote YES WE CAN!! have a global depression if we really continue to work at it ... at his blog at FT.com:
I used to be optimistic about the capacity of our political leaders and central bankers to avoid the policy mistakes that could turn the current global recession into a deep and lasting global depression. Now I’m not so sure.
I used to believe that the unavoidable protectionist and mercantilist rhetoric would not be matched by protectionist and mercantilist deeds. Protectionism was one of the factors that turned a US financial crisis into a global depression in the 1930s. Protectionism imposes large-scale structural sectoral dislocation, as exporters are ejected from their foreign markets and domestic producers that depend on cheap imported imports suddenly find themselves to no longer be competitive, on top of the global effective demand failure we are already suffering from.

Paul Krugman argues:

But these are not normal conditions. We’re in the midst of a global slump, with governments everywhere having trouble coming up with an effective response.

And one part of the problem facing the world is that there are major policy externalities. My fiscal stimulus helps your economy, by increasing your exports — but you don’t share in my addition to government debt. As I explained a while back, this means that the bang per buck on stimulus for any one country is less than it is for the world as a whole.

And this in turn means that if macro policy isn’t coordinated internationally — and it isn’t — we’ll tend to end up with too little fiscal stimulus, everywhere.
...............
Let’s be clear: this isn’t an argument for beggaring thy neighbor, it’s an argument that protectionism can make the world as a whole better off. It’s a second-best argument — coordinated policy is the first-best answer. But it needs to be taken seriously.

What’s the counter-argument? Don’t say that any theory which has good things to say about protectionism must be wrong: that’s theology, not economics.
.....................
But there is a short-run case for protectionism — and that case will increase in force if we don’t have an effective economic recovery program.

Well, now we go back to Buiter, and quote:

We can go down in history as the generation that created the Great Depression of the Noughties. Just keep on beating the protectionist drums. Keep on the footdragging that prevents effective qualitative and quantitative monetary policy easing in the Eurozone and the UK. And go ahead with unsustainable fiscal stimuli in the US, the UK and elsewhere that will spook markets, push up long-term interest rates and raise the spectre of sovereign default by countries not belonging to the group of usual suspects. Yes we can! I hope we won’t.

So, the
national economic egoism goes "rational"? Export-mania thesis? Don't fool ...

UPDATE @ 16:45 (14:45 GMT): Krugman still argues re protectionism, but unites with Willem Buiter in fear of depression ....

UPDATE 2 @ 20:50 (18:50 GMT): Krugman defends:

First of all: my piece was NOT an endorsement of protectionism — it was an explanation that there is an economic case for it, but also that there is a strong political economy case (which I consider dominant) against acting on that economic case. It was, in short, an attempt to be intellectually honest.
