It is not we non-interventionists who are isolationsists. The real isolationists are those who impose sanctions and embargoes on countries and peoples across the globe because they disagree with the internal and foreign policies of their leaders. The real isolationists are those who choose to use force overseas to promote democracy, rather than seek change through diplomacy, engagement, and by setting a positive example.
I do not believe that ideas have an expiration date, or that their value can be gauged by their novelty. The test for new and old is that of wisdom and experience, or as the editors wrote "historical reality," which argues passionately now against the course of anti-Constitutional interventionism.
