But critics then and since have blasted Jefferson and his immediate successor, James Madison, for a series of ideologically driven blunders. Jefferson envisioned a largely autarkic nation with yeoman farmers serving as its economic and political backbone. That notion was at odds with an America whose wealth was increasingly gleaned from foreign markets. The Republican policy of wielding partial or complete trade embargos as a diplomatic weapon repeatedly backfired, inflicting grievous damage on America's economy and culminating with an unnecessary war with Britain that was devastating to America's power and wealth, if not its honor. Despite their philosophical and political differences, Federalists and Republicans alike proved capable enough at the art of power when they headed the nation. They implemented a spectrum of mostly appropriate means, first to win independence and then to consolidate and eventually expand American wealth and territory.
