In the original framework of Professors Acemoglu and Robinson, the government is unable to oppress the revolution once it is brought about. However, actual civil wars are unpredictable. With this notion, I introduce uncertainty depending on military expenditures of the government. Then an interesting argument follows: if the likelihood of successful oppression is sufficiently larger than a certain level of destruction rate and there are cheap-but-effective devices such as biochemicals, citizens in a dictatorial country may have a trade-off between economic prosperity and domestic military threats.
