This chapter turns to the analysis of the practice of justifying force in the ‘semi-peripheries’, i.e., in non-‘European’ States. The purpose is to see whether legal arguments were also developed and whether they differed from the ones brought forth to justify bellicose endeavours in the ‘centre’. It focuses on four case studies: the European intervention during the Greek War of Independence (1827); the French expedition in Lebanon and Syria (1860); the western intervention during the Boxer Revolt in China (1901); the Monroe doctrine and the Roosevelt corollary with special attention to their application in Nicaragua in the early twentieth century (1909–1912). It argues that, although these interventions rarely gave rise to full-blown wars, the justifications brought forward did not substantially differ from the ones used in the ‘centre’. States, in fact, carefully developed legal arguments and evidenced how their actions were meant to redress a previous offence.
