Commentators such as David French and Ross Douthat call this a “cold civil war.” The phrase flatters. America today has fury without formations: hashtags where brigades should be, white papers where orders of battle once lived. Authority is fraying, yet too strong to collapse outright, which makes the violence more insidious. It is Italy’s Years of Lead (Anni di piombo), or Argentina’s grim seventies: a low, filthy hum of political violence. Enforce the law swiftly and without favorites.
