Admit that each country was at fault for causing the war
Each country participating in the war needs to pay a fine of 5-10 million dollars to pay for any damages caused in the war (must be distributed equally amongst each country impacted by the war)
Each country must cut its army to 100,000 men
Each country is only allowed to own 6 dreadnoughts, no submarines, and no air forces
(I'm not sure about the last one but hopefully this helps!)
