genocidal countries

yeah we should get involved with the countries at risk of a genocide. Genocide is a Huge deal! in order to get rid of an entire type of person you have to kill quite a few people to do so. soooo if a country is thinking about this act ,powerful countries should try to stop it. cause if they dont then theres absoultely nothing stopping them from killing tons of innocent people. i feel like this is an obvious question but hard to explain
