As genocide is most likely to occur during war, one of the best ways to reduce the chances of genocide is to address the root causes of violence and conflict: hatred, intolerance, racism, discrimination, tyranny, and the dehumanizing public discourse that denies whole groups of people their dignity and their rights.
Some actions ain't supposed to escalate into something so big and deep as this, but peaceful resolutions isn't a language people understand so well. They will use force, destroy lives and properties, then turn to peace after lots of damages have been done already. Life is a struggle and the strong won't stop eliminating those who would stand on their way.
Sometimes the root cause of these wars are not dealt with and you know why? Some countries still benefit from the war because it still business for them to sell their war equipment or exchange it for other benefit. When you see war going on, there are people who benefit from it and that is the reason we may never get war free countries, you must have to see some instigations of war to enable them have some sells. I don't support genocide and it is in the hands of government to stop this incessant killings of innocent people.
