Actions characterized as "blowback" often involve logic and reason. Just like military action is often indefensible murder of civilians ("war crime") but not always, decentralized violence on the grounds of defending or pursuing a national project can be senseless or meaningfully goal-directed.

To be very clear, my inclination in all of this is not to use the comparison to exonerate blowback but to condemn violence, organized and disorganized, in general. But I think it's a hard moral road to hoe to say states can do war but stateless collectivities may never pursue goals with violence.
