Why Peace Is So Tricky for Humans

peace when we heard a word "peace" for human especially for this time we always hear about war at some country. I think a bit hard to say that peace will happen soon. peace is so tricky for humans because they have a selfisheart and do not want to understand another human. Like our close living relatives, chimpanzees and bonobos, humans are hardwired come into conflict with one another, often violently. Even so, like our ancestors, we also have the capacity to resolve fights; something that one anthropologist says has evolved along with our societies over the millennia.

usually if someone has lost something from his life because his selfisheart. he would think in two ways. the first one is they want to apologize and forget about everything he did or he would do something worse than he did before. if he has lost his family for example because  something that he has done like war he would regret his act and he would not do that again because he has lost something from his life. and if he will not regret because his act he would do the worse thing than he did before. peace is very tricky for human because human a bit hard to say sorry or apologize because they just think about theirself not another people.

I think human for right now a bit hard because they would feel ashame to recognize their problem. they do not want feel ashame because they are afraid. if they say sorry for the first time that means that their enemy would think that they are a looser.  it will be hard if someone would not say sorry or recognize their mistake first.

Human Conflict: Winning the Peace

 Competition and conflict both among and within species, for food or a place to live or a mate, are implicit in the process of evolution and thus intrinsic to our biology. But like many other animals, we are also social beings, and, like them, we have evolved behaviors to avoid the detrimental effects of excessive intraspecies violence. human usually do their best for wining the peace.
The groups we consider ourselves to be part of, our “ingroups,” are critical to our understanding of “self ” and categorization of “other” or “outgroups”. everybody wants winning the peace because everybody want to leave without war and always safe with family without treat from another country.

usually people will do anything they want. like snatch power or country from someone. it could be a big problem if human can not control theirself. many children have lost their hapiness because war and die, because their selfisheart. not just children the woman are the victim.
This special section looks at the past and future of conflict and the kinds of data needed to analyze it. However, our interest in conflict must ultimately be to facilitate peace. There are many examples of neighboring societies that do not war against each other, and they appear to have worked in part by expanding the “us.” 

I think that human have to control theirself because it is not about theirself. its about another human too. and they have to finish their problem in better way like apologize, confrence or meeting to solve their problem without victims again. it would be better than always do war. i think the problem can be solve if we know the way to solve it better without violence.
