The author demonstrates that humanitarian intervention is not a modern invention, but it has roots that go at least as deep into 19th century politics and international relations. Three historic cases are analyzed: Greek War of Independence (1821-1832), when an Allied force of British, French and Russian vessels defeated an Ottoman armada in the Battle of Navarino; expedition of Austrian, British, French, Prussian and Russian forces into Syria during the 1860 Druze–Maronite conflict; and Russo-Turkish war of 1877-1878, where Russia was driven by the ideas of pan-Slavism and protection of the Christian population on the Balkans.
Indeed, certain events of the 19th century were paralleled during the crises of the next century. While speaking about the Ottoman atrocities in Bulgaria, Disraeli called such atrocities "inevitable, when wars are carried on in certain countries, and between certain races" and was unwilling to intervene, same as Warren Christopher, Bill Clinton's Secretary of State, some 117 years later spoke in Congress about "atrocities on all sides" in Bosnia. Disraeli dismissed the consular report about the situation in Bulgaria as based on "coffee-house babble brought by an anonymous Bulgarian", and Neville Chamberlain later referred to Nazi Germany's ambitions in Czechoslovakia as a "quarrel in a far-away country between people of whom we know nothing".
Gary Bass suggests that because "massacres turn out to be the regular way of the world, the world will need a regular response to them". And when Slobodan Milosevic insisted on the national sovereignty as the right of the government to do whatever it wishes within its borders, he was forgetting the fact that a century ago Serbians appealed to the European powers for rescue in the same way that the Kosovars appealed to the US and NATO in 1998-1999.
