Chain ganging is a term in the field of international relations describing the elevated probability for interstate conflict or conflagration due to several states having joined in alliances or coalitions.
The agreed principles of such alliances typically include mutual defence clauses requiring that, in the case of one member state suffering military attack from another power, all members must declare hostilities against that offending power. The result of such an arrangement is an elevated probability for an international conflagration, since the case of an actor attacking another power would almost certainly trigger, whether intentionally or not, a multinational conflict potentially involving many more actors than the original two states which had attacked and been attacked, respectively.
