I say Israel - and I hope this is taken in an utterly nonpartisan way, which takes absolutely no position vis-a-vis the legitimacy of either conservatism or the Israeli state. I just think some core aspects of Israeli government and society are in line with mainstream US conservatism: a free-market liberal democracy of course, but with formal religious-ethnic affiliation, compulsory military service with training on firearms (and licensing to possess same) for all citizens, and a generally hawkish stance on questions of military and defense. They are also highly security-oriented, some would say in a much more effective way than the US government, and its security apparatus employs profiling techniques which almost undoubtedly have a racial component (<span>and </span><span>conservatives would no doubt want to insist that these two facts are directly related). I believe that taxation rates are roughly on par with that in the US, if not a bit less... though not nearly as low as Switzerland. </span>
