"The most striking thing to me is the platform's complete repudiation of the kind of limited government principles espoused in the domestic chapters of the platform. The title of the foreign policy platform is "American Exceptionalism" so you can already tell where this is going: the same federal government that the party does not trust to manage the domestic economy, or whose actions have a distorting and largely negative effect when acting at home, suddenly transforms itself into God's appointed deputy for spreading freedom to the world's peoples.
It's a breathtaking transformation and one that is, ideologically at least, nonsensical. The national security state is the antithesis of limited government."
