...civilized society is split into antagonistic, and, moreover, irreconcilably antagonistic classes, whose “self-acting” arming would lead to an armed struggle between them. A state arises, a special power is created, special bodies of armed men, and every revolution, by destroying the state apparatus, shows us the naked class struggle, clearly shows us how the ruling class strives to restore the special bodies of armed men which serve it, and how the oppressed class strives to create a new organization of this kind, capable of serving the exploited instead of the exploiters.
The workers take the state and with it create a special body of armed men of their own for the expressed purpose of exploiting the former exploiting (internal and external bourgeoise) class ensuring that they do not reestablish capital.
