I believe that it is in our nature that we bicker and fight with another. That any peace is destined to fail given a relatively short amount of time. That the attempt of trying to have all people from all walks of life cooperate is a fool's errand (though admirable task). I believe that the root cause of our hatred of another derives from [i]fear[/i]. Not the fear of something scary, but the fear of someone different. Someone with a different culture/values than you. 

"Those Mexicans are crossing our boarder illegally and taking our jobs."|"Soviet Russia is shipping nuclear missiles to Cuba."|"Terrorists are posing as immigrants/refugees to get within our boarders".

 We fear something that may or not be happening that will lead to negative results of varying degree. Fortunately the solution is simple. Education. Unfortunately, the solution will be difficult to implement. Not only will absolutely everybody need to be informed, but it must be ingrained within their consciousness to diffract bias. There is also the fact that people are naturally resistant to the idea of being wrong, sometimes to the point of violence. People would rather listen to confirmation of their beliefs than facts. (I mean, anti-vaxxers still exist despite the monumental evidence to the contrary)
