To get an idea for which regions of the world are currently threatened by genocide, check out the United States Holocaust Museum's "Who's at Risk?"

The U.S should get involved with regions that are threatened by genocide for many reasons. One reason is that if one entire race or religion is lost, we lose a culture and things that may benefit us in the future. For example we may lose herbs or medicine which may be the cure diseases that are fatal now. Also if a lot of people get killed, one of the people that died might have grown up to be a scientist that developed a way to cure hereditary diseases. So those kids that got killed in the Holocaust could have been the saviors of many lives.
