Yes, and as my favourite philospher Thomas Hobbes (1588-1679) rightly summed up:
"Hereby it is manifest , that during the time men live without common Power to keep them all in awe, they are in a condition which is called Warre; and such a warre, as is of every man, against every man. For WARRE , consisteth not in Battell onely, or the act of fighting; but in a tract of time, wherein the Will to contend by Battell is sufficiently known: and therefore the notion of Time, is to be considered in the nature of Warre; as it is in the nature of Weather. For as the nature of Foul weather , lyeth not in a showre or two of rain; but in an an inclination thereto of many dayes together: So the nature of War, consisteth not in actual fighting: but in the known disposition thereto, during all the time there is no assurance to the contrary. All other time is PEACE."
Hobbes, T. Leviathan pp. 185, 186 Penguin (1651)
