The “Thucydides Trap”

Filed under: Books, China, History, Military, USA — Tags: , , , , , , — Nicholas @ 03:00

At History Does You, Secretary of Defense Rock provides a handy explanation of the term “the Thucydides Trap”:

In the world of international relations, few concepts have captured as much attention — and sparked as much debate — as the “Thucydides Trap”. Brought to prominence by Harvard political scientist Graham Allison, the term suggests that conflict is almost inevitable when a rising power threatens to displace an established one, a dynamic often invoked to frame the strategic rivalry between the United States and China. Lauded as a National Bestseller and praised by figures like Henry Kissinger and Joe Biden, Allison’s Destined for War: Can America and China Escape Thucydides’s Trap? has become a staple of policy discussions and academic syllabi. Yet beneath the widespread acclaim lies a deeply flawed analysis, one that risks oversimplifying history and perpetuating a fatalistic narrative that could shape policy in dangerous ways. Far from an inescapable destiny, the lessons of history and the nuances of modern geopolitics suggest that the so-called “trap” may be more myth than inevitability.

The term “Thucydides Trap” is derived from a passage in the ancient Greek historian Thucydides’ work History of the Peloponnesian War, where he explained the causes of the conflict between Athens (the rising power) and Sparta (the ruling power) in the 4th century BC. Thucydides famously wrote

    It was the rise of Athens and the fear that this instilled in Sparta that made war inevitable.

Allison defines the “Thucydides Trap” as “the severe structural stress caused when a rising power threatens to upend a ruling one”.1 More articles by Allison using this term previously appeared in Foreign Policy and The Atlantic. The book, published in 2017, was a huge hit, being named a notable book of the year by the New York Times and Financial Times while also receiving widespread bipartisan acclaim from current and past policymakers. Historian Niall Ferguson described it as a “must-read in Washington and Beijing”.2 Senator Sam Nunn wrote, “If any book can stop a World War, it is this one”.3 A brief search on Google Scholar reveals the term “Thucydides Trap” has been cited or used nearly 19,000 times. In 2015, Australian Prime Minister Malcolm Turnbull even publicly urged President Xi and Chinese Premier Li Keqiang to avoid “falling into the Thucydides Trap”.4 One analyst observed that the term had become the “new cachet as a sage of U.S.-China relations”.5 The term has become so prominent that it is almost guaranteed to appear in any introductory international politics course when discussing U.S.-China relations.

Allison wrote in his essay “The Thucydides Trap: Are the U.S. and China Headed for War?” in The Atlantic published in 2015, “On the current trajectory, war between the United States and China in the decades ahead is not just possible, but much more likely than recognized at the moment” forewarning, “judging by the historical record, war is more likely than not”.6 A straightforward analysis of the 16 cases in the book and previous essays might indicate that, based on historical precedent, there is approximately a 75 percent likelihood of the United States and China engaging in war within the next several decades. Adding the additional cases from the Thucydides Trap Website would still leave a 66 percent chance, more likely than not, that two nuclear-armed superpowers will go to war with one another, a horrifying and unprecedented proposition.7

With such alarm, it’s no surprise that the concept gained such widespread attention. The term is simple to understand and in under 300 pages, Allison delivers a sweeping historical narrative, drawing striking parallels between events from ancient Greece to the present day.8 International Relations as a field often struggles to break through in the public discourse, but Destined for War broke through, making a broad impact on academic and popular discourse.

QotD: Sparta’s military reputation in the Peloponnesian War

Filed under: Europe, History, Military, Quotations — Tags: , , , , , — Nicholas @ 01:00

Herodotus’ work was well known, even in antiquity, and he set the tone for all subsequent retellings of the Persian wars (despite the frequent complaints by later ancient authors that Herodotus’ reliability was – let’s say, complicated. I don’t want to give the wrong impression: Herodotus is a valuable source, just one that – like all sources – has his own agenda at play). The Spartan reputation thus seems to be the product of half a century spent fighting far, far weaker opponents, combined with one very skilled propagandist with an agenda.

That reputation was already deeply held even by the early stages of the Peloponnesian War, such that Thucydides notes that “Nothing that happened in the war so shocked the Greeks so much as” the surrender of 120 Spartiates at Pylos/Sphacteria, instead of dying with their weapons in their hands (Thuc. 4.40.1). The Athenians had, in the event, managed to trap a force of Spartans – Spartiates and other Laconians – on an island and harassed them with arrow fire from a distance, never closing with them, until the Spartans surrendered. This is, I must stress, in the context of a war that obliterated entire poleis, shredded the diplomatic fabric of Greece and was by far the largest war between Greeks that any of them knew of. But this, the shattering – if just for a moment – of the Spartan reputation, that was what shocked people. The image of Sparta – whatever the reality – was that deeply set.

Thucydides, amusingly, relates that some Greeks were so shocked that they couldn’t believe it, and one ally of Athens inquired to the Spartiates – then held as captives in Athens – if perhaps what had happened was that all of the brave men (you know, the real Spartiates) had been felled by the arrows, to which the Spartans responded, “an arrow would be worth a great deal if it could pick out noble and good men from the rest, in allusion to the fact that the killed were those whom the stones and the arrows happened to hit” (Thuc. 4.40.2).

QotD: Logistical limits to Spartan military action against Athens

Perhaps the most obvious example of poor Spartan logistics is their almost comical inability to sustain operations in Attica during the Peloponnesian War. This is, to be clear, not a huge task, in as much as logistics problems go. The main market in Sparta is 230km (c. 140 miles) from the Athenian agora; about a ten-day march, plus or minus. Sparta’s major ally in the war, Corinth, is even closer, only 90km away. The route consists of known and fairly well-peopled lands, and the armies involved are not so large as to have huge logistics problems simply moving through Greece.

During the first phase of the Peloponnesian War, called the Archidamean war, after the Spartan king who conducted it, Sparta invaded Attica functionally every year in an effort to inflict enough agricultural devastation that the Athenians would be forced to come out and fight […] The core problem is that it just isn’t possible to do a meaningful amount of damage in the short campaigning season before the army has to go home.

And I want to be clear just how long they bang their head against this rock. The Spartans invade in 431, besiege a minor town, accomplish nothing and leave (Thuc. 2.18-20), and in 430 (Thuc. 2.47), in 429, because of a plague in Athens, they instead besiege tiny Plataea (Thuc. 2.71ff) and then leave, but in 428 they’re back at it in Attica (Thuc. 3.1), and in 427 (Thuc. 3.26), and in 426 but turn back early due to earthquakes (Thuc. 3.89). But they’re back again in 425 (Thuc. 4.2), leaving each time when supplies run out. Sparta mounts no attack in 424 because Athenian naval raiding forces them to keep the army at home (Thuc. 4.57); in 423 they have a year-long truce with Athens (Thuc. 4.117). They only finally suggest the creation of a permanent base in Attica in 422/1 (Thuc. 5.17) but the war ends first (they’ll actually fortify a small outpost, Decelea, only when the war renews in 413).

Thucydides is in several cases (e.g. Thuc. 3.1.3) explicit that what causes these armies to fail and disperse back home is that they run out of supplies. They are two days – on foot! – from a major friendly trade port (Corinth), and they run out of supplies. Their last invasion was six years after their first and they still had not resolved the logistics problem of long-term operations in what is effectively their own backyard.

Ahh ancient Greece, it has been entirely too long. Today we’ll take a look at the foundational work of my entire career path — Thucydides’ History of the Peloponnesian War, a book that almost single-handedly set the standard for how we engage in historical inquiry. Also it has the added benefit of being about Ancient Greece so win-win!

SOURCES & Further Reading: History of the Peloponnesian War by Thucydides, Histories by Herodotus, Hellenica by Xenophon, and the 4 straight years I spent studying this in university — Boy do I love doing a video about a topic I’m specifically trained in.

Thucydides again

Filed under: Greece, History, Politics — Tags: , , , — Nicholas @ 03:00

David Warren found a dip into Thucydides was at least as informative on political issues today as any current “reporting”:

What a week it has been, at least in the yellow world of journalism and politics. I have had nothing new to say on anything — at least I hope to have said nothing new, for my intention in commenting on passing events is simply to repeat the old gnomes which they freshly illustrate. Thucydides, into whose works I privately dipped last Tuesday, was as up-to-date as anything I found “breaking” on the Internet.

Consider, for instance, the career of the Athenian general (then Spartan, then Persian, then Athenian again), Alcibiades — more sinned against than sinning, and more sinning than sinned against, by turns. A large man, persistently underridden by the mean and small; a hero and no saint. Loved to the point of worship by the crowds; hated by the umbrous, to the point of madness; and always “in the news.”

A polarizing figure, as we’d say today; who, for his impieties, was finally run down by a mob. They set fire to the cottage where he’d retired with his mistress. (The Spartans commissioned the mob by one account; the young lady’s parents by another.) Boldly emerging from the flames to confront the whole tribe of his adversaries, he died in a hail of arrows. The gods let only Stalin die in his sleep. (Or so we thought until we got more information.)

What Thucydides can teach us about fighting ebola

Filed under: Africa, Europe, Greece, Health, History — Tags: , , , , — Nicholas @ 10:43

In The Diplomat, James R. Holmes says that we can learn a lot about fighting infectious diseases like ebola by reading what Thucidides wrote about the plague that struck Athens during the opening stages of the Peloponnesian War:

Two panelists from our new partner institution, a pair of Africa hands, offered some striking reflections on the fight against Ebola.

Their presentations put in me in the mind of … classical Greece. Why? Mainly because of Thucydides. Thucydides’ history of the Peloponnesian War isn’t just a (partly) eyewitness account of a bloodletting from antiquity; it’s the Good Book of politics and strategy. Undergraduates at Georgia used to look skeptical when I told them they could learn ninety percent of what they needed to know about bareknuckles competition from Thucydides. The remainder? Technology, tactics, and other ephemera. Thucydides remains a go-to source on the human factor in diplomacy and warfare.

But I digress. Ancient Greece suffered its own Ebola outbreak, a mysterious plague that struck Athens oversea during the early stages of the conflict. And the malady struck, perchance, at precisely the worst moment for Athens, after “first citizen” Pericles had arranged for the entire populace of Attica, the Athenian hinterland, to withdraw within the city walls. The idea was to hold the fearsome Spartan infantry at bay with fixed fortifications while the Athenian navy raided around the perimeter of the Spartan alliance.

[…]

That’s where the parallel between then and now becomes poignant. Thucydides notes, for example, that doctors died “most thickly” from the plague. The Brown presenters noted that, likewise, public-health workers in Africa — doctors, nurses, stretcher-bearers — are among the few to deliberately make close contact with the stricken. Relief teams, consequently, take extravagant precautions to quarantine the disease within makeshift facilities while shielding themselves from contagion. Sometimes these measures fail.

Now as in ancient Greece, furthermore, the prospect of disease and death deters some would-be healers altogether from succoring the afflicted. Selflessness has limits. Some understandably remain aloof — today as in Athens of yesteryear.

Teams assigned to bury the slain also find themselves in dire peril. Perversely, the dead from Ebola are more contagious than living hosts. That makes disposing of bodies in sanitary fashion a top priority. As the plague ravaged Athens, similarly, corpses piled up in the streets. No one would perform funeral rites — even in this deeply religious society. Classicist Victor Davis Hanson ascribes some of Athens’ barbarous practices late in the war — such as cutting off the hands of captured enemy seamen to keep them from returning to war — in part to the plague’s debasing impact on morals, ethics, and religion.
