throughout history Europe has been waring against one another, however there seems to be some seeing of sense from the bigger parties as in the best part of 70 years no wars were started, ie france v England spain v france etc yet you say in the east they would still be waring if left to there own devices anyway so why what causes so much unrest between those people you mentioned? I know there have been other wars but Europe has managed to remain war free relatively
the conflicts in the middle east now are actually for the same reason, some countries want pieces of other nations and some countries want to keep what they have, that and ethnic groups fighting for supremacy. lasting peace will only come after establishing a new balance between all these nations and ethic groups.
