ABSTRACT
The Internationalists is a history of the legal right of war—jus ad bellum —from Grotius to ISIS. According to the Modern State Conception, a legal system must contain internal bureaucracies, such as prosecutors, police, and jails that enforce the law through the threat or use of violence. Outcasting is ubiquitous in modern international law, from the World Trade Organization to the Universal Postal Union to the Montreal Protocol. By demonstrating that violations of international law were—along with all other legal wrongs—historically redressed by war, The Internationalists seeks to reorient the discussion about compliance with international law. Grotius is also the patron saint of the International Court of Justice in The Hague.
