"We consider the conditions of peace and violence among ethnic groups, testing a theory designed to predict the locations of violence and interventions that can promote peace… Switzerland is recognized as a country of peace, stability and prosperity. This is surprising because of its linguistic and religious diversity that in other parts of the world lead to conﬂict and violence…Don’t hold your breath, you New England researchers.
Our analysis shows that PEACE DOES NOT DEPEND ON INTEGRATED COEXISTENCE, BUT RATHER ON WELL DEFINED TOPOGRAPHICAL AND POLITICAL BOUNDARIES SEPARATING GROUPS. Mountains and lakes are an important part of the boundaries between sharply deﬁned linguistic areas…
Our analysis supports the hypothesis that VIOLENCE BETWEEN GROUPS CAN BE INHIBITED BY PHYSICAL AND POLITICAL BOUNDARIES. A similar analysis of the area of the former Yugoslavia shows that during widespread ethnic violence existing POLITICAL BOUNDARIES DID NOT COINCIDE WITH THE BOUNDARIES OF DISTINCT GROUPS, but PEACE PREVAILED IN SPECIﬁC AREAS WHERE THEY DID COINCIDE.
The success of peace in Switzerland may serve as a model to resolve conﬂict in other ethnically diverse countries and regions of the world.”
Since 1923, the Cultural Marxists and their heirs the PC Crowd have been preaching the exact opposite of the stone bl**ding obvious stuff you posit here. And, seeing as the politically correct and their brothers-in-arms, the globalist elite, have ruled the roost in the western world for almost half a century, we won’t be seeing an end to the destruction of our ‘boundaries’ by the alien hordes of Asia, Africa, the West Indies and eastern Europe any time soon.
