On the other hand it does feel like all these events feel like situations that need constant inputs of "energy" to be sustainable - war relies on firepower, a repressive regime requires efforts to keep the populace content enough to not revolt (or enough firepower to quash revolution attempts), so given enough time the system would return to a more stable equilibrium.
