Building the Con on Regime Change: Sovereignty, the Record and the Agent Problem

Con on this topic has more evidence than it knows what to do with. Iraq, Libya, Afghanistan, decades of covert operations, a large academic literature on foreign-imposed regime change: the record is there for the taking. The danger is that teams read the record and assume it wins on its own. It doesn’t. A good Pro team will concede every failed intervention, point out that none of them met its conditions, and ask what any of it has to do with the principle. If your Con case can’t answer that, you’ll lose to a Pro with half your evidence.

This post builds a Con case that engages the principle directly. The core idea is simple: Con doesn’t have to prove regime change is always wrong in some imaginary world. Con has to prove that the United States, the actor in the resolution, isn’t justified in using force to remove authoritarian leaders, because the method predictably fails, the precedent causes harm beyond the case, and the actor can’t be trusted to apply the conditions honestly.

The framework: justification has to survive the real world

Start by setting a standard that makes the record relevant. A strong Con framework says that an action is justified only if it can be justified with foreseeable consequences taken into account, by the actor who would actually carry it out. That sounds obvious, but it closes the escape hatch Pro wants to use. Pro wants to defend a principle floating above history. Your framework says a principle of war has to be judged by what happens when real governments apply it.

You can ground this in just-war thinking itself. The traditional criteria include a reasonable probability of success and proportionality, both of which are about consequences. You can also cite John Stuart Mill’s 1859 essay "A Few Words on Non-Intervention," which argued that liberty won by a people’s own efforts is more likely to last than liberty handed to them by foreign arms. Mill supported intervention in some cases, so don’t overclaim him, but his central worry is exactly your case: outside force can remove a tyrant without creating the conditions for freedom.

Contention one: regime change fails for structural reasons

Your first contention should argue that forcible regime change fails in predictable ways, and that the reasons are built into the act rather than being accidents of bad planning. This is what turns the record from a list of anecdotes into an argument.

There are three main mechanisms. First, removing a leader by force usually destroys the institutions a successor needs. Authoritarian regimes tie the army, police, civil service and courts to the leader. Removing him often means dismantling them, and the vacuum fills with armed groups. The 2003 decisions in Iraq to dissolve the army and purge members of the Baath Party from public life are the clearest example: hundreds of thousands of trained, armed and angry men were suddenly unemployed, and many joined the insurgency. Pro will call this bad planning. Your answer is that the planning problem is inherent. Keeping the old institutions means keeping the regime’s machinery, and destroying them means chaos. There’s rarely a good middle option.

Second, the new government inherits a legitimacy problem. A leader installed or enabled by a foreign power is seen as that power’s client, which weakens him at home and invites resistance. Third, the intervener faces a commitment problem. Building a stable state takes years or decades. Democratic publics lose patience long before then, and everyone in the country knows it, so local actors wait the intervener out. Afghanistan is the textbook case: the Taliban were removed in 2001 and retook Kabul in August 2021 while US forces were still withdrawing.

The best evidence for this contention comes from political science that studies regime change as a category rather than case by case. Alexander Downes’s Catastrophic Success (2021) argues that foreign-imposed regime change often goes wrong, including by setting off civil war and conflict between the intervener and the leader it installed, for reasons close to the structural problems described above. Lindsey O’Rourke’s Covert Regime Change (2018) examines US regime change efforts during the Cold War and finds that they frequently failed to deliver the outcomes Washington wanted. Cut cards from these books, not summaries of them, and understand their methods well enough to defend them. A Pro team that has read the same books will ask you about the exceptions.

The impact of this contention is a probability argument. Pro’s principle includes a reasonable prospect of success. If regime change fails for structural reasons, that condition is rarely met. Pro can’t just assume it away.

Contention two: the precedent problem

Your second contention should argue that US regime change causes harm beyond the country where it happens, by weakening the rules that restrain everyone else. This is where sovereignty comes in, but as a consequence argument rather than an abstract right.

The prohibition on the use of force in Article 2(4) of the UN Charter is one of the most important rules in the international system. It doesn’t stop all wars, but it raises the cost of aggression and gives the world a common standard to judge it by. When the most powerful country in the world claims a right to remove governments it judges to be authoritarian, other powers claim similar rights. When Russia annexed Crimea in 2014, Vladimir Putin pointed to Kosovo as a precedent. You don’t have to believe the comparison was fair. The point is that precedents get used by people you wouldn’t choose, in ways you wouldn’t endorse.

There’s a second precedent effect worth running: the nuclear lesson. Libya’s leader gave up his weapons of mass destruction programs in 2003 and was overthrown with NATO help in 2011. North Korean officials and state media have pointed to Libya as a reason never to give up nuclear weapons. If the US claims a right to remove authoritarian leaders by force, authoritarian leaders have the strongest possible incentive to get a nuclear deterrent. The principle Pro defends makes proliferation more attractive to exactly the regimes you’d least want to have the bomb.

The impact here is magnitude. Pro weighs the lives saved in a specific intervention. You weigh the erosion of the rule against aggression and the incentive to proliferate, which affect every country and last far longer than any single war.

Contention three: the agent problem

Your third contention is the one that should win you most rounds, and it’s the one many Con teams under-develop. The resolution doesn’t ask whether force is justified. It asks whether the United States is justified. Even if a principle of humanitarian regime change is sound in the abstract, the US can’t be trusted to apply it, and a principle that can’t be applied responsibly by the actor holding it isn’t justified for that actor.

The evidence for this contention is about selectivity and history. The US has supported authoritarian governments when they served its interests, including during the Cold War and in its present-day partnerships in several regions. It has used force or covert action against governments that weren’t committing atrocities, including elected ones, as in Iran in 1953. It has also declined to act against atrocities when intervention didn’t fit its interests, as in Rwanda. The pattern suggests that American decisions about regime change track American interests, not the moral conditions Pro describes.

Pro will answer that abuse doesn’t disprove the principle, the way false claims of self-defense don’t disprove self-defense. Your response is the difference between an individual and a superpower. When one person falsely claims self-defense, a court can review the claim. When the US claims its intervention meets the conditions, there’s no court. The Security Council may be vetoed, and the US decides for itself. A principle with no neutral judge becomes whatever the most powerful actor says it is. That’s why legitimate authority is part of just-war theory, and why the US acting alone fails it.

Framed this way, the agent argument doesn’t depend on anyone thinking the US is uniquely bad. It depends only on the observation that no great power can be trusted to be judge, jury and enforcer in its own cause. That’s a much easier claim to defend, and most judges will find it reasonable.

Engaging the limiting case

Pro’s best moment will come when it asks: "So you’d stand aside during the next Rwanda?" You need an answer that isn’t "yes, and too bad." There are three good options, and you can combine them.

First, stopping a genocide isn’t the same as removing a leader. Force can protect civilians through safe zones, peacekeeping, no-fly zones or strikes on the forces carrying out the killing, all without trying to remove the government. The resolution is specifically about removal. If Pro’s example of justified force is protecting civilians, they’ve drifted off the resolution. Second, Libya shows what happens when a protective mission turns into regime change: the intervention that began to protect civilians in Benghazi ended with Gaddafi’s death and years of civil conflict. Some scholars, including Alan Kuperman, have argued that the intervention prolonged the war and increased the killing. Third, even in the hardest case, the question is whether removal by the US is the best available response compared with multilateral, authorized or non-removal options. Pro rarely shows that.

This answer lets you agree that atrocity is terrible and that the world should respond, while still negating the resolution. Judges like Con teams that take the moral stakes seriously. They don’t like Con teams that sound indifferent to mass murder.

Writing the case

A four-minute Con constructive might run like this. Open with about twenty seconds of framework: justification must account for foreseeable consequences and for the actor who applies it. Give contention one, structural failure, about a minute and a half, with the three mechanisms and academic evidence. Contention two, precedent, gets about a minute, with the rule against aggression and the nuclear lesson. Contention three, the agent problem, gets the remaining time, with selectivity, the lack of a neutral judge and the difference between individual self-defense and great-power intervention.

If you’re short on time, cut contention two before contention three. The agent argument is harder for Pro to answer and more directly tied to the text of the resolution. Precedent arguments are also easier to extend in rebuttal as offense against Pro’s case, so you can bring them in later if you need them.

Frontlining the agent argument

Because the agent argument is your best offense, it will draw Pro’s best responses. Prepare for three. The first is the self-defense analogy: people abuse the right to self-defense, but it’s still a real right. Your answer, covered above, is that self-defense claims get reviewed by a neutral court, and great-power interventions don’t. The second is domestic checks: Congress, the courts, the press and voters constrain the President. Your answer is that those checks have rarely stopped a war once it started. They mostly operate afterward, when the damage is done, and they judge the war by its costs to Americans, not by whether it met moral conditions abroad.

The third response is the alternative: if not the United States, then who? Pro will argue that insisting on a neutral judge means nobody acts. Don’t accept the binary. Multilateral action with regional backing, Security Council authorization when it can be obtained, and protective force that stops short of removal are all real options that Pro’s framing hides. You don’t have to prove those options always work. You only have to show that US unilateral removal isn’t the only alternative to doing nothing, which breaks Pro’s strongest emotional appeal.

Write each of these frontlines out in two sentences and practice them until you can deliver them in fifteen seconds. In a close round, the agent argument lives or dies on how quickly and cleanly you can answer Pro’s responses in second rebuttal, before the summary collapse.

What Con needs to win in the back half

By summary, collapse to the argument that best exploits Pro’s framework. If Pro defended a narrow principle, go to the agent argument and structural failure: the conditions are almost never met in reality, and the US can’t be trusted to say when they are. If Pro defended a broad principle, go to the record and precedent: Pro is defending a doctrine with a terrible track record and enormous systemic costs.

Your final focus should give the judge a clean choice. Pro offers a principle that works in theory and a hope that the United States will apply it well. Con offers the record of what happens when it tries, and the reasons that record won’t change. The resolution asks about the real United States in the real world. On that question, the evidence is on your side.
