Arming a few dictators but not others: The politics of UK arms sales to Chile (1973–1989) and Argentina (1976–1983)
The United Kingdom imposed an arms embargo on Chile in 1974 but not on Argentina after the 1976 coup, despite brutal military dictatorships in both countries. What explains this difference? What can this difference reveal about the determinants of government decisions regarding arms exports? Using mainly archival evidence, this article demonstrates that this difference is explained by a stronger advocacy network in the United Kingdom campaigning on Chile, which was largely due to a greater identification of the British left with the Chilean struggle. The hub of this network was the Chile Solidarity Campaign, which mediated the influence of the transnational anti-Pinochet movement on the UK government. These findings suggest that shared values or identities make transnational issues more likely to resonate with domestic audiences. Evidence also indicates the importance of activists’ connections with gatekeepers, focus on specific arms deals, and demonstrated causal chains between arms exports and repression.
