I always wonder why battle loses and planet glassing cause riots. Sure, from one hand such events cause population anger growth, but from another hand such kind of fury was always directed to invaders but rarely toward their OWN goverment.
So using such inverted logic (which is common for humans, especially for womankind

) one can think that losed battles and destroyed planets will lead to patriotic feelings explosion and extreme bloodlust.
That is a good concept for Masochistic happiness type
