Larison dissects Gingrich's foreign policy:
Many Republicans flatter Gingrich by treating him as one of the party's intellectuals, but Gingrich frequently shows that he is unable or unwilling to make crucial distinctions in his treatment of international problems. He complains on his campaign website that "we currently view Iraq, Afghanistan, and the many other danger spots of the globe as if they are isolated, independent situations," and that America "lacks a unified grand strategy for defeating radical Islamism." But these conflicts are largely separate from one another, and there is no such thing as a monolithic, global, radical Islamism that can be addressed by one strategy. No conflicts around the world can be properly understood except by focusing on local circumstances, but for Gingrich, the ideological emphasis on a unified global threat takes priority over proper analysis.
Which makes him the perfect antithesis of conservatism. Conservatism is concerned with reality, which it understands shifts with culture, history, region and all the immense complexities of human life. When a conservative approaches a problem like Jihadist violent Islam, he will seek first a grasp of its divisions, analyze the most effective way of defusing and disarming and fighting it, ensure that a strategy in one part of the world is not necessarily salient to another, grapple with unintended consequences, and so on. What Gingrich does is the opposite. What he always longs for is the absolute, eternal principle, the clarifying concept, the rhetorical rallying cry that speaks to the ideological gut rather than the reality-based frontal cortex. And Gingrich's notion of foreign policy – making John Bolton his secretary of state – is essentially a policy of open hostility to the entire world, including allies who differ, and a maximalist military solution to most problems.
Part of me wonders if Gingrich couldn't heighten the absurd contradictions of contemporary "conservatism" and help accelerate its destruction. But the damage he could do as president vastly outweighs the uncertain benefits of that particular scenario.
