Okay, say you control a powerful nation. With technology around WW2.
Say some other nations have the same tech, but not as powerful. Let's say three others.
But one BIGASS MOTHER FUCKER whom has ruled the region for a long time, with nuclear bombs, an army that dwarfs all, and a home fort that cannot be broken in a siege without massive casualties, say they get a new guy on the throne.
He clearly says that he doesn't want people speaking out or shit like that, and threatens violence. But he promises no government interference in daily life if you do as you're told.
What do you do, avoid bloodshed and genocide, or rebel and enter a war which hundreds of thousands will die?
