Libertarians in the United States feel a new-found momentum on the issues most important to them. Their preferred candidate for the presidency, Rand Paul, has consistently ranked high in pre-election opinion polls. America has never seemed so reluctant to intervene overseas. And the federal government has faced significant pushback for its intrusive surveillance methods, into whose net many Americans have fallen.
However, the growing non-interventionist impulse of Americans highlights a shortcoming in the libertarian position: its insularity. Most libertarians are “America firsters” in that their values seem to apply only at home. That would be fine, except when it has a bearing on the single issue that most defines libertarians, namely liberty.
