Y Combinator backs its first defense startup, Ares Industries

Defense Spending, Threats, and “Defense” vs. “Offense”

• Some argue defense is a “growth industry”; others note US defense as % of GDP is historically low.
• Supporters say more defense innovation is needed to deter authoritarian states and avoid over‑consolidated contractors.
• Critics counter that the US is already “bellum paratum,” highly militarized, and often uses force offensively rather than defensively.
• Debate over whether cruise missiles can ever be truly “defensive,” with some saying it’s about use, not tech.

Ethics, Foreign Policy, and Democracy vs. Dictatorship

• Multiple comments highlight US involvement in coups and regime change (Latin America, Iran, Operation Condor) as evidence that US power isn’t always used to defend democracy.
• Others stress they still prefer a world led by imperfect democracies over authoritarian regimes.
• One view: democracies can eventually admit and compensate for wrongs (e.g., Japanese internment); counterpoint: even dictatorships sometimes repudiate past crimes.

War Crimes, Accountability, and International Law

• Concerns raised about lack of accountability for US war crimes, including legal shielding from international courts.
• Examples cited: drone strikes, lethal strikes programs, Yemen airstrikes linked to US/UK weapons, and laws enabling resistance to ICC jurisdiction.
• Defenders emphasize terrorists and hostile actors using civilians as shields; critics say this is overused to excuse civilian casualties.

Global Peace, Deterrence, and the UN

• One camp says the world is increasingly hostile; another claims it’s the most peaceful era ever.
• Credit for avoiding world wars is variously given to nuclear deterrence, UN institutions, or both; some call UN largely ineffective.
• Debate over whether Russia–Ukraine is a proxy war and whether Ukraine giving up nukes enabled invasion.

YC, Startups, and Defense Industry Structure

• Some see YC’s move into weapons as natural: huge, sticky budgets; inefficient incumbents; government spending rising as % of GDP.
• Others see it as technofascist drift and “working for warlords,” noting Silicon Valley’s long defense roots.
• Clarification that YC has funded defense-adjacent startups before; Ares is distinct for making actual weapons.
• An industry insider describes structural barriers for new defense firms: slow payments, reliance on a single (USG) customer, and procurement rules that favor big, waterfall-style contractors.

Technology, Drones, and Proliferation Risks

• Discussion of cheap cruise missiles/drones potentially creating a “conventional MAD” scenario.
• Some speculate Ares may be closer to low‑cost FPV drones than traditional cruise missiles.
• Worries about second‑order effects: exports to partners (e.g., Israel), use in conflicts like Yemen, and domestic militarization of police, though cruise‑missile use by police is seen as unlikely but not unthinkable.
