Extremism also depends on context. In many societies resistance to universal ID cards is not considered extreme at all. And fortunately many folks still realize the great fallacy of "No innocent person ever has a need to conceal his identity."

But I'm afraid it's hard to see how any correlation you might find between high surveillance societies and avoiding wars is unlikely to be causal. Having less crime I can certainly see a link. However, it is about personal freedom and human rights that we are having a debate.
