Book excerpt: Countering our divisive times, this innovative book makes the conservative case in favor of international organizations and cooperation. Dalibor Rohac persuasively argues that far from undermining national sovereignty, the mechanisms of international cooperation have been instrumental to humankind’s freedom, prosperity, and peace. Moreover, he shows that unlike the caricature of international cooperation as a top-down imposition, in reality it is characterized by extreme institutional diversity. Its structures have typically emerged from the bottom up, in response to concrete challenges transcending national borders. Moving beyond empty political rhetoric, Rohac's meticulous research and clear analysis assess and explains the strengths, flaws, and relevant trade-offs of different forms of global governance. A powerful rebuttal to the temptations of nationalist populism, his work is a call to arms for thoughtful people on the center right to defend the central tenets of the post-WWII international order.
