What does
war conceal?
War is usually described through aims, victory and defence. Less visible is its full account: people, money, the environment, institutions and individual responsibility. This project brings those layers together without pretending that one statistic settles the argument.
A concise English overview. The full articles and evidence library are currently in Czech.

The answer without a shortcut
Would moving 10% of military spending solve global problems?
No. Roughly USD 288.7 billion would be large enough to expand several humanitarian, health, education, science and climate programmes. The comparison shows the scale of a political choice. It does not prove that money can be transferred immediately, absorbed efficiently or produce a guaranteed result.
01 / Budget comparison
What is the opportunity cost of military expenditure?
The slider compares a share of one year of world military expenditure with published budgets and financing needs. Each card states its period; annual budgets and multi-year programmes are not treated as identical.
Interactive model
Allocate USD 288.7 billion
Source amount: USD 288.7 billion. Changing one field adjusts the others proportionally so the total remains 100%.
Education
USD 57.7bn
allocated amount60 % of UNESCO's estimated annual financing gap
Health
USD 57.7bn
allocated amount2.6× of the annual target for tuberculosis funding
Science
USD 57.7bn
allocated amount6.5× of the NSF annual budget
Climate adaptation
USD 57.7bn
allocated amount16–19 % of UNEP's annual-needs estimates from two methods
Water and sanitation
USD 57.7bn
allocated amount51 % of estimated annual capital costs
The model only allocates the amount and compares orders of magnitude. It does not account for absorption capacity, political feasibility, construction time, or the fact that security spending cannot be removed unilaterally without changing risks.

Method note: the calculator combines annual budgets, multi-year programmes, financing needs and current investment volumes. It compares orders of magnitude; it does not claim that any selected share is immediately available. Source comparisons remain in USD.

Research findings, with their limits
Short English summaries of the latest additions. The linked articles are in Czech; the original sources below are in English.
War also affects a country's ability to grow food
A study published on 24 September 2026 combines cropland maps for 2000–2020 with over 460,000 conflict events in 155 countries. Its difference-in-differences estimate and matching analysis use different comparisons. They cannot be added together; the modelled calorie potential is not a count of people actually fed.
Li et al. · original studyRead the article in Czech →Who gets mediation before war?
A random sample of self-determination disputes in 1991–2015 shows that preventive mediation is shaped by low-level violence, conflict in neighbouring countries and geopolitical constraints. The study examines where mediation occurred, not whether it prevented war. Its findings do not cover every type of political crisis.
Cunningham et al. · 6 March 2026Read the update in Czech →Violations and children are different counts
The UN report dated 16 June 2026 records 38,558 violations verified in 2025. A child can experience several violations; some incidents happened in earlier years and were verified later. These are documented cases, not a complete count of all harm.
UN · S/2026/357Read the article in Czech →Reconstruction is part of the model
A study published on 20 March 2026 models the Israel–Gaza conflict’s footprint, including pre-conflict infrastructure and future reconstruction. Its 33.2m tonnes CO₂e estimate includes the narrower scope 1 and 2 estimate; it is not all emissions already released.
Neimark et al. · study and scopeRead the update in Czech →Spending does not measure effectiveness
The UN’s June 2026 launch material compares aid for peace with military expenditure over two decades. The ratio excludes many domestic investments in safety. Assessing prevention requires defined outcomes, a credible comparison and uncertainty, not a promise of universal returns.

Six parts of the argument
Law and ethics
When can force be justified?
The strongest case for defence, and the legal and moral limits it must meet.
Read the argument Human and environmental accountWhat does a military budget omit?
Death, injury, displacement, toxic damage, reconstruction and lost investment.
Read the account Psychology and its limitsHow is obedience produced?
Authority, language, divided tasks and the contested interpretation of Milgram.
Read the analysis Oral historyWhat can personal testimony establish?
Experience can reveal mechanisms and moral conflict, but cannot establish prevalence.
Read the limits Policy and institutionsWhat can reduce the risk of war?
Defence, law, diplomacy, resilient institutions, prevention and arms control.
Read the framework Editorial standardHow are facts separated from judgement?
Primary sources, explicit uncertainty, strong counterarguments and public corrections.
Read the method02 / Defence and law
Rejecting war does not require abandoning the attacked.
Article 2(4) of the UN Charter prohibits the threat or use of force. Article 51 preserves individual and collective self-defence after an armed attack, and Chapter VII gives the Security Council powers to respond to threats to peace.
This is not a blank cheque. International humanitarian law still requires distinction, proportionality and precautions. The strongest objection to a pacifist thesis is that credible defence may deter aggression and protect people who cannot safely refuse violence.
UN Charter · Article 51UN Charter · Chapter VIIICRC · conduct of hostilities03 / Costs and impacts
War is a major cause of forced displacement, not the only one.
Persecution, mines, destroyed infrastructure, distrust and climate pressures can continue after fighting ends. Refugee numbers therefore cannot be derived from military expenditure alone.
One in every 70 people on Earth was forcibly displaced at the end of 2025.

Safe return also requires law, functioning institutions, housing, work and long-term trust.
Military emissions
A 2022 model estimated a 3.3–7% range, with about 5.5% as its central estimate. It is an extrapolation from incomplete data, not a global inventory.

05 / Voices from service
Testimony reveals experience. It does not establish prevalence.
The Czech edition presents five archived accounts concerning civilian protection, conscience, refusal and the consequences of service. They can show how people understood a situation and which moral pressures they remember.
They cannot tell us how typical those experiences were. Time since the event, retrospective reconstruction, self-selection, survival and archive selection all limit generalisation. Personal testimony is therefore kept separate from experimental, legal and statistical evidence.
Oral History Association · Core PrinciplesImperial War Museums · collections06 / Prevention
UN and World Bank models estimate that one dollar invested in prevention could save up to sixteen dollars in later costs in some scenarios.
This is not a universal rate of return. It depends on the conflict, timing and institutional quality. Prevention complements the defence of people under attack; it is not a promise that every aggressor can be persuaded.

Archival source and context07 / Editorial standard
A strong argument is not enough. It must be checkable.
Major claims link to primary studies, official statistics or archival records. Facts, estimates, interpretations and hypotheses are labelled separately. The strongest reasonable counterargument is presented before an editorial judgement.
What is known
State the conclusion and immediately say what the evidence does not establish.
What it contests
Present the strongest reasonable objection, not a weak substitute.
Where it comes from
Link to the original record and explain what the number actually measures.
When we are wrong
Date the change, explain the reason and preserve a visible correction record.
World military expenditure reached USD 2,887 billion in 2025.
A published aggregate with a defined year, currency and methodology.
SIPRI · 2025 expenditureThe figure reveals opportunity costs, not an immediately transferable fund.
Programmes differ in timing, capacity, governance and the risks they address.
Earlier prevention may reduce both violence and later public costs.
Plausible and modelled in some settings, but not guaranteed in every conflict.
