Overview & Core Thesis
In The Virtual Weapon and International Order, Oxford scholar Lucas Kello delivers one of the most intellectually rigorous challenges to classical international relations (IR) theory in the digital age.
While strategic skeptics (like Thomas Rid in Cyber War Will Not Take Place) argue that cyber attacks rarely meet Clausewitzian thresholds of true warfare, Kello argues that this traditional lens misses the point entirely. Cyber weapons are fundamentally altering the global balance of power precisely because they operate in the vast, volatile grey zone between war and peace—a state Kello terms "Unpeace."
Key Theoretical Contributions
1. The Concept of "Unpeace"
Kello argues that classical IR theory splits inter-state relations into a binary: Peace or War. Cyber operations defy this construct:
They inflict systemic, cumulative economic, social, and political damage well above tolerable peacetime competition.
Yet, they intentionally remain below the physically destructive, lethal threshold that triggers conventional armed response or Article 5 collective defense.
This continuous mid-spectrum rivalry (unpeace) erodes state sovereignty, national power, and institutional trust without ever declaring formal war.
2. The Breakdown of Classical Deterrence
Traditional nuclear and conventional deterrence relies on attribution, clear red lines, and threat of retaliation. Kello demonstrates why this framework fails in cyberspace:
Attribution & Anonymity: Hiding behind proxies, non-state actors, or false flags weakens credible threat signaling.
Offense Dominance & Volatility: Cyber capabilities favor the attacker, making passive defense nearly impossible against persistent, evolving threats.
Democratization of Force: Non-state actors, criminal syndicates, and sub-state groups can wield strategic counter-state force once reserved solely for sovereign nations.
Comparison: Kello vs. Rid
| Strategic Perspective | Thomas Rid (Cyber War Will Not Take Place) | Lucas Kello (The Virtual Weapon & International Order) |
| View on Cyber Operations | Cyber attacks are sub-state aggression (sabotage, espionage, subversion), not true war. | Cyber weapons represent a revolutionary shift that breaks classical IR frameworks. |
| Analytical Lens | Clausewitzian (requires physical violence, open political coercion, and lethality). | Systemic & Strategic ("Unpeace" mid-spectrum conflict below armed violence). |
| Implication for Policy | Cyber threat is often sensationalized; existing statecraft frameworks suffice. | Western policy is failing because legacy deterrence cannot handle grey-zone aggression. |
Strategic Proposals (Looking to Striking Back)
In his follow-up work, Striking Back: The End of Peace in Cyberspace and How to Restore It, Kello moves from diagnosis to solution:
Reject "Cyber Legalism": Passive reliance on international norms and treaties fails against adversaries (like Russia or China) who exploit grey zones.
Punctuated Deterrence: Rather than tit-for-tat retaliations or passive defense, Western nations should execute cumulative, targeted, and decisive cyber counter-operations to alter an adversary's strategic calculus.
Final Verdict
Lucas Kello’s work is essential reading for national security planners, cyber strategists, and policy analysts. It provides the crucial theoretical bridge between technical cyber security and high-level international strategy.
