After describing NAFTA as 'the worst trade deal maybe ever signed anywhere', Donald Trump's election seemed to represent the final nail in the coffin for North American economic integration. Following a decade of stagnation, however, Trump's victory presents a timely opportunity to reconsider North American integration and evaluate NAFTA's democratic track record in Mexico. In this book, Pablo Calderon Martinez presents a detailed analysis of NAFTA's influence as a political tool for democracy in Mexico. Extending beyond a mere economic or social exploration of the consequences of NAFTA, Calderon Martinez uses a three-tiered analysis based on causality mechanisms to explain how the interactions between internationalisation and democratisation unfolded in Mexico. Calderon Martinez's analysis demonstrates that Mexico's internationalisation project under the framework of NAFTA gave shape to, if not made, Mexico's democratisation process. An original and timely resource for scholars and students interested in understanding how - in cases like Mexico where transitions to democracy are characterised by a finely poised balance of power - small influences from abroad can make significant long-lasting differences domestically.
