The bullet box indeed. The bullet box created the republic (revolutionary war) and the bullet box preserved the union (civil war).
"War is the continuation of politics." In this sense, war is politics and war itself is a political action; since ancient times there has never been a war that did not have a political character.... However, war has its own particular characteristics and in this sense, it cannot be equated with politics in general. "War is the continuation of politics by other . . . means." When politics develops to a certain stage beyond which it cannot proceed by the usual means, war breaks out to sweep the obstacles from the way.... When the obstacle is removed and our political aim attained the war will stop. Nevertheless, if the obstacle is not completely swept away, the war will have to continue until the aim is fully accomplished.... It can therefore be said that politics is war without bloodshed while war is politics with bloodshed. - Mao
Hopefully, it won’t come to that “court of last resort”.
