I admire a country were the response to such attack is "we need more democracy".
That would be nice,
except that's not what mainstream political science literature says about terrorism. Read Quan Li's paper for more information (this appears to be an earlier version though, you could find a more recent one on JSTOR, but I don't want to rely on people having that), but to summarize,
democracy is correlated with terrorism. Why? Though democracy can co-opt extremist elements by granting them a say in their society, it also ensures that the country cannot use coercive measures to stop terrorists in their tracks. Executive constraints is also correlated with higher terrorism: according to Quan Li, this is because executives can more effectively deal with terrorists if they aren't constrained by politics, either through appeasement or through suppression.
Press freedoms are also correlated with higher terrorism, and Norway has very high Press Freedoms out there, though there is debate whether press freedoms are caused by an "underreporting bias" (dictators can suppress instances of terrorism occuring) or through the presses hyping up terrorist attacks and making them more successful, thereby encouraging other terrorist attacks int he future.
More democracy is good, but at some point, I'd admire a country that cares about political science research.
(I'm sorry, I am writing my Masters' Thesis on the relationship between democracy and terrorism, so I didn't really like people praising democracy, especially at a time like this.)
EDIT: (To be fair, Quan Li attempted to show that certain elements of democracy causes terrorism, and not democracy in of itself. For example, proportional representation and high voter turnout is correlated with less terrorism. If you control for these factors, then democracy does reduce terrorism. However, I'm using an updated dataset and is trying to replicate Quan Li's findings. So far, um, no real success. And it's pretty hard to think of a Democracy with no Press Freedoms and low Executive Constraints, as these two elements do correlate with higher terrorism.)
EDIT2: If you have access to a school library or JSTOR or anything that allows you access to full peer-reviewed articles, search for "Does Democracy Promote or Reduce Transnational Terrorist Incidents?" The main difference I'm seeing is that in the peer-reviewed article, he did not bother looking at civil liberties, saying that it's tangential to something more important: executive constraints.
