The moments that decided it
DAY 218
Portugal signals openness to talks
This moment mattered because momentum shifted durably toward Spain: original objectives look unachievable and domestic political pressure.
Think it would go differently?
This run assumed no allies, winter, full mobilization for the attacker and partial for the defender, and no nuclear weapons. Change any of that and watch it play out day by day on the map.
