An important point about tit-for-tat conflicts: most sides regard themselves as the victims, no matter which sides objectively behave worse. This victimization mentality adds to outrage on other sides.
Many individuals act as if they would rather be killed in a tit-for-tat conflict, than stop the tit-for-tat downward spiral.
Tit-for-tat conflicts are highly probable in and among multicultural white societies where a) pan-Europeanism is considered verboten, b) mass media are extremely one-sided, with narrow, poorly reasoned Overton windows, c) leaders habitually blame shift and eye poke on domestic issues, then extend those habits to foreign policy issues, d) ethically truthful dissenters are slurred and banished as extremists, e) massive power imbalances exist among grandstanding, dark triad ruling groups and the peoples they rule over, f) ruling groups despise the people they rule over.
The more dark triad elites interact, the more conflicts increase. Remember to include interactions with diversity plus proximity equals war.
Bait-and-switch, divide-and-screw is the habit of the militaristic, multicultural, oligarchal beast.
