We keep looking at ancient peace treaties the way we look at self-help books. As if people in 1259 BCE had figured something out about human nature that we've since forgotten.
They weren't wiser. They were trapped. The Egyptian-Hittite treaty between Ramesses II and the Hittite king Hattusili III arrived when both empires had bled themselves white fighting over Syria.
Neither could win alone, and both faced the Sea Peoples. Raiders destabilizing the eastern Mediterranean in ways neither kingdom could manage separately. They signed because exhaustion plus external threat left them no other option.
This formula repeats everywhere it actually works. The United States and Soviet Union didn't negotiate seriously until the Cuban Missile Crisis proved mutual annihilation was real. The Good Friday Agreement in 1998 happened because the IRA had no path to victory and unionists had no leverage to crush them entirely. Shared weakness, not shared wisdom.
Shared weakness, not shared wisdom.
But most modern disputes don't have that structure anymore. One side usually retains asymmetric advantage and believes it can still win. When Israelis and Palestinians enter talks, one party holds military superiority and settlement expansion while the other holds nothing equivalent. And no external threat exists that would destroy both if ignored. The question isn't whether you've both discovered the virtue of peace, it's whether you've both discovered the certainty of mutual ruin and face an enemy larger than each other. If you haven't, one side is waiting for leverage to shift, and it probably will.
