Cold War Tension

The world shares one number: a tension gauge from 0 to 100 that sits at the top of the Conflicts page. It is not your country's reading, or your rival's; it is the temperature of the whole standoff, and everything from readiness postures to arms budgets moves with it.

The five bands

Band	Reading	What it feels like
DETENTE	low	Genuine thaw. Summits, treaties, trade across the divide.
CALM	below the midpoint	The ordinary cold war. Watchful, armed, stable.
ELEVATED	around the midpoint	Incidents accumulate. Diplomats work late.
CRISIS	high	The world holds its breath. Miscalculation gets expensive.
BRINK	highest	The final band. Nobody plans past it.

The exact thresholds between bands are visible on the gauge itself; the band label is what most of the world's machinery reacts to.

What raises it

Tension climbs when the world gives it a reason:

Nuclear tests. Every device test spikes tension, and bigger devices spike it harder. See The Nuclear Programme.
Escalation. Climbing the rungs of an active proxy war raises the standing pressure, not just a one-off spike.
Crises. Each active world crisis keeps the temperature up while it burns.
The world's arsenals. The total warhead count across all programmes sets part of the floor. An armed world is a tense world even on a quiet week.

What lowers it

Time. With no new provocations, tension relaxes turn by turn.
Detente moves. Deliberate de-escalation, stand-downs, and diplomatic thaw apply relief directly.
Standing down. Descending the escalation ladder and resolving crises lowers the floor that tension decays toward.

Note the shape of that: spikes fade, but tension never decays toward zero. It decays toward a floor set by how armed and embroiled the world actually is. If the arsenals are huge and the proxy war is hot, no amount of waiting reads as peace.

What it does

Tension is a cause, not a scoreboard:

Readiness. Higher bands tighten the world's defence condition; militaries sit closer to alert.
Procurement demand. A frightened world buys arms. Defence contractors and procurement both feel the band.
Detente goodwill. Thaw is a resource. High tension burns the goodwill that cooperative diplomacy needs.

Playing it

You do not control the gauge; you contribute to it. A well-timed test, a rung of escalation, a crisis left to burn: each is a decision about the world's temperature, and the whole world pays the bill together. The powers that read the gauge best are the ones that choose when to be provocative, not the ones that are provocative by accident.
