If the needle is firmly in the green, a slight shift towards red in response to Fukushima might mean commissioning some studies and announcing a budget for upgrading the safety features.
But if the needle is just barely into the green, a slight shift moves it into the red and that means shutting them down. So yes, in a country where public opinion is divided, it is not out of the question to swing from yes to no in response to the biggest emergency since Chernobyl. I'm not sure about the phrase "knee-jerk," though. It may seem like a drastic move, like a leg kicking in response to a small tap, which implies a response out of [proportion to the stimulus.
However, perhaps the response is in proportion, it's just that when the needle is right on the dividing line, it only takes a small move to get from green to red?
Now that I write my thoughts out, I obviously agree with you :-)
They had decided to extend the life of the reactors just last year. No new risk inherent to their design has been exposed. No new tsunami or earthquake risk in Germany has been exposed.
I agree with the person quote in TFA (despite the fact that his statement may be a political play as well) :
"She just wants to get through the provincial assembly elections," said Social Democrat leader Sigmar Gabriel, accusing her of playing political tactics with people's fears.

This gives his statement about Merkel's move just being politics more weight
Personally, I'd feel a lot safer if all nuclear plants were turned off forever. Sure, the chance of something going horribly wrong is low, but if it goes wrong it is a big big mess. Just too horrible to warrant any of the advantages that nuclear power has.
And still I'd rather be exposed to all of those risks than worry about one nuclear explosion. As I said, the consequences can be just too horrible, for too many people.
I'd love to move on from fossil fuels to something else, but not something that can cause such disasters.
Most of the mercury in fish originates from coal-burning power plants. [1]
Do you fly? A single airliner accident can kill hundreds at a time, but cars kill many more people a year. Somehow it's more acceptable for people to die one or two at a time in great numbers.

No matter how you compute statistics, a nuclear meltdown is a big downside risk. It can happen, and if it happens it's extremely destructive. It's an event with a small chance of occurence but with great consequences.
That's qualitatively different from something like traffic accidents. The chances of those happening are much higher, but if they happen, they affect at most a few people, They won't turn your city into a 'wildlife reserve' for years to come.
Even though the total amount of people that die of traffic accidents is higher, to me it's less scary. The risks are more manageable: you have some degree of control over it (drive safely) and the consequences are visible.
