The Fuse, Not the Foundation

The Capture

The four Deccan sultanates hated each other. They only ever united once, in 1564–65, and only because Ramaraya of Vijayanagar had grown big enough and arrogant enough to frighten all of them at the same time. They crushed him at Talikota — and within weeks they were back to carving at each other's gains. The phrase that crystallised while building the Talikota alliance and the disunity-doom thesis: the common enemy is a fuse, not a foundation. It burns down to the destruction of the target and then there is nothing left holding the structure up. The alliance was exactly as durable as Ramaraya's life.

The Live Wire

• First wire (obvious): shared threats unite rivals. Old news.
• Second wire (the spark): the failure mode is the lesson. A coalition built on a common enemy inherits, the day after victory, the problem of what binds it now — and usually the answer is nothing. The winner of a common-enemy coalition is handed a vacuum, not a kingdom. The sultanates "won" Talikota and immediately resumed losing to each other, which is the slow road to 1686.
• Third wire (the reach): this is the same shape as Aurangzeb destroying the sultanates and inheriting the Marathas — winning removes the thing that was organising you. Victory as a disorganising event. Where else does the destruction of the enemy destroy the victor's own coherence?

Where It Wants to Go

A handshake/thread connecting coalition-fragility, the common-enemy frame, and "victory as a disorganising event" — possibly a cross-domain page if the mechanism generalises beyond statecraft (it smells like it does: revolutions after the king falls, movements after the cause wins).
