Evidence on the Effectiveness of Terrorism

Readers of this blog will know that I like the works of Max Abrams, and regularly blog them. He has a new paper (full paper behind paywall) in Defence and Peace Economics, 22:6 (2011), 583–94, "Does Terrorism Really Work? Evolution in the Conventional Wisdom since 9/11":

The basic narrative of bargaining theory predicts that, all else equal, anarchy favors concessions to challengers who demonstrate the will and ability to escalate against defenders. For this reason, post-9/11 political science research explained terrorism as rational strategic behavior for non-state challengers to induce government compliance given their constraints. Over the past decade, however, empirical research has consistently found that neither escalating to terrorism nor with terrorism helps non-state actors to achieve their demands. In fact, escalating to terrorism or with terrorism increases the odds that target countries will dig in their political heels, depriving the nonstate challengers of their given preferences. These empirical findings across disciplines, methodologies, as well as salient global events raise important research questions, with implications for counterterrorism strategy.

EDITED TO ADD (2/14): The paper.

It worked in Malaysia (1960), Isreal (1948) and Ireland (1922) and arguably N. Ireland in the 90s - simply make it uneconomic, in money and casualties, for the big powerful country to continue opposing you.

Of course the same strategy hasn't worked in Afghanistan

It seems to me that this assumes the terrorists' stated goal are the actual goal.

NobodySpecial: There's no way in hell Northern Ireland is any terrorist success.

It's still part of UK and barely got some limited government, headed by an Unionist no less, and with barely any more power than Government of Ireland Act 1914 already established.

Meanwhile Scotland is getting its independence referendum in two years without ever blowing a single bomb.

IRA has been a total failure by any reasonable standard.

Since I'm not going to pay $46 (plus tax) for a 12-page paper, I have to go on the abstract.

Terrorism sometimes works and sometimes doesn't, and its objectives aren't always obvious. Two examples:

IRA terrorism didn't achieve the stated objective (the whole of the island of Ireland united in one nation) despite decades of intermittent rebellion and terrorism. But in the end, it did achieve concessions for the IRA and for the tribe that supported them in Northern Ireland, where a former IRA leader is now Deputy First Minister.

I don't know what the objective of 9/11 was, but the Bush administration eagerly responded by doing such stupid things that the US has utterly lost what moral authority it had in the world. And the Bush regime's 'war on terror' is with us to this day: the DHS harasses US citizens everywhere they go in their own country, and the US is so resented in the rest of the world that there are many places where it's unwise for them to travel. Was that success?

Does the response to the Soviet invasion of Afghanistan count as terrorism?

@NobodySpecial-

I don't know what you're thinking of in Malaysia in 1960, but the other two conflicts are more typically considered civil wars (or possibly, in the case of Israel, a regional war - 1948 starts in a civil war and ends in the 1948 Arab–Israeli War). One major difference between terrorists and fighters in a war, even if they use similar tactics to achieve similar ends, is that the later often have broad support in a significant population.

Posted by: Fred P at January 26, 2012 11:56 AM


The N.Ireland conflict was not just about a united Ireland, it was about civil rights. Irish Catholics were treated as second class citizens.

The IRA did achieve all its goals, except a united Ireland. Which become a mute point when the UK & Eire joined the EU.

There's a problem: what is terrorism?

It used to refer to attacks or threats on civilians for the purpose of achieving a political end. But now it seems to include attacks on military targets if the targeted military is the US, Israel or NATO (this kind of thing used to be called guerilla warfare), and it seems to exclude attacks on civilians in many cases (attacks on abortion providers or Iranian nuclear scientists don't seem to count, even though the victim is civilian and the goal is political).

Posted by: Joe Buck at January 26, 2012 12:22 PM


In Israel I meant the 'spirited' opposition to the British colonial forces by Irgun which resulted in their political victory in 1948.

The same process happens: Terrorists attack, the powerful country decies it can beat them and pour money and troops into the conflict.

At some point somebody does the sums and wonders if the cost and casualties for 'defending' a worthless bit of sand/bog is worth it.

Then the rhetoric changes from "no negotiation with terrorists" to "an ongoing peace discourse". Then they pull out and it's congratulations and Nobel peace prizes all round.

Whether it's rebels in Malaysia, Irgun in Israel, ANC in South Africa, IRA in N. Ireland the odds do seem to be on the side of the local 'freedom fighters' in the long run.

So what then is the reason for terrorism? A shiny object to point your most dangerous potential adversaries at? A way to get them killed off (political purge by proxy)?

Posted by: bcs at January 26, 2012 12:46 PM


The 9/11 hijackers weren't insurgents in the same sense - but if their aim was to shock and scare ordinary Americans and lure the American administration into a long and expensive (politically, militarily and financially) ill-defined war on terror.

Then I would say they have succeeded rather well.

Posted by: NobodySpecial at January 26, 2012 12:51 PM


As someone who is having a lot of fun with transforms and eigenvectors...

Terrorism doesn't work, unless your goals are congruent to the natural responses of terrorism defense.

Thus, its very hard to use terrorism to spread Islam to the US. Its very easy to use terrorism to make the US spend a lot of money.

@NobodySpecial:

I'm not sure why you think Irgun brought Israel it's independence, as opposed to a thousand other factors that were at play?

For one thing, allowing a Jewish state was the mandate the British received to begin with. Another was the between 1944 and until Israel was formed, Irgun was completely neutralized by the Jewish organization, which is exactly the time period you state as when it worked.

@NobodySpecial

I dont buy it. How the British treated Irish Catholics was immoral. The aims of the IRA (not their methods) were justified.

The UK government didn't give up because it cost too much. The UK government (slowly) changed laws to prevent discrimination against Irish Catholics. The original IRA stopped because Irish Catholics where treated as equals in the UK, and no longer treated like scum.

If the IRA had gone down the path of Gandhi I think the civil rights issues would have been resolved quicker as the IRA would have held the moral high ground.

Posted by: alan at January 26, 2012 2:16 PM


They still seem to have been pretty effective at planting bombs in 1946.

I wasn't being specific about Irgun/ Hagana/ Stern/ People's front of Judea - just that acts which would be regarded as terrorism, were strongly correlated with the British leaving.

Of course this doesn't imply any causation. Perhaps, just like Afghanistan, they were simply waiting for a legitimate political authority to be ready to be take over - and the bad publicity at home from IED attacks on ordinary soldiers had no bearing.

"...political science research explained terrorism as rational strategic behavior..."

The problem with this line of thinking is the word "rational." While human beings are capable of reason, we are not (by and large) rational creatures. We rarely deduce the best course of action for anything. Instead, we make quick, instinctive judgements.

It's really easy to understand terrorists: they hate their enemies and want to hurt them.

Posted by: Peter at January 26, 2012 2:22 PM


@alan - there are lot of background reasons for the NI peace accord.

The improved economic situation - new industry making unionist dominated shipyards irrelevant. A new labour government with less political baggage. The EU making the difference between Ireland and Britain less relevant. An ageing IRA leadership wanting some of the comforts of political success.

If it was purely due to changes in the laws against catholics the problem would have been solved in 1829!

But the financial costs of the Baltic exchange bombing and attacks on the City of London brought a LOT of political pressure to bear in a way that a few dead civilians in a distant province didn't.

Posted by: NobodySpecial at January 26, 2012 2:26 PM


Every fascism state has its convenient 'terrorist' scapegoat, be it from the capitalist sleeper cells in Soviet russia to the jews in Nazi germany. These terrorists are not the threat.

Ask yourself who the real terrorists are? How about the NDAA, Patriot act, rendition, waterboarding, TSA, ACTA warmongering pushers?

Actions talk louder than rhetoric.

is this the same paper but form free ?

Overly broad thesis

Posted by: Your Advisor at January 27, 2012 5:41 AM


Thus validating a Chinese maxim I once heard which, roughly translates to "He who resorts to violence only does so because he lost the argument".

Posted by: Sean at January 27, 2012 3:00 PM


@james

I think it is, but I am unsure whether this is for public consumption. Found it by googeling the title, which is a normally good way to find a free tech-report version of papers.

For Google to have it as first hit, there should be quite a few links to it though.

Terrorism also worked for Moses.

"Let my people go, or else"... worked against the State.

Funny how Americans forget this..

Posted by: Maj Variola at February 15, 2012 1:31 PM


@ Maj Variola,

Funny how Americans forget this

It's even funnier how all the WASP Nations forget this as well.

Science changes technology not people so history tends to be quite predictable from the human asspect, hence as we get older our many feelings of deja vue.

As was once observed,

"Those that fail to learn the lessons of history are condemned to relive them".

Or as Shakespear would have Mark Anthony say,

"The evil that men do lives after them, the good is oft interned with their bones!"
