Used. Paperback. If you have ever wondered why Americans are from Mars and Europeans are from Venus, Robert Kagan’s brilliant geopolitical primer offers a provocative peek into the widening transatlantic chasm. This sharp little volume unpacks how shared history and differing military might birthed two radically divergent worldviews—one lounging in a postmodern paradise while the other patrols the ramparts. Kagan brilliantly diagnoses the mutual exasperation turning allies into ideological strangers without pretending to neatly bandage the rift. Grab a copy if you want to understand why Uncle Sam and the European Union are currently speaking entirely different foreign policy languages.
