US–Latin America’s security: moving through an inflection point?

Recent elections in Latin America, such as those of Mauricio Macri in Argentina, Horacio Cartes in Paraguay, and the impeachment process of Dilma Rousseff in Brazil, point to a new direction in Latin American politics and away from the “hard left;” they also point to a new momentum in the security relationship between the US and Latin American countries. Former US President Obama’s 2016 trip to Cuba and Argentina was a clear demonstration of this new security paradigm and also a clear indication that there is a new momentum brewing in the US towards a rethinking and reshaping of security strategies and mindsets. This article will explore the multidimensional security relationship between the US and Latin American countries in light of recent changes in the US’ posture toward the region.     

UNCLOS and maritime security: the “securitisation” of the South China Sea disputes

This Critical Comment seeks to situate the United Nations Convention on the Law of the Sea (UNCLOS) within the context of South China Sea (SCS) dispute. Bearing in mind that maritime actions of the main disputants – China, Vietnam, and the Philippines – increasingly “securitise” these long-standing disputes and vice versa, the study examines the concept of a maritime “regime complex.” Whereas efforts have being made to examine UNCLOS and indeed the dispute within the framework of a maritime “regime complex,” the key finding shows that the increased “securitisation” of the disputes makes it difficult to envisage effective engagement of UNCLOS as a resolution mechanism. It will also reveal that China's firmly established expansionist agenda in the SCS region is indicative of Beijing's susceptibility to compromise a diplomatic solution to these long-standing disputes. These discoveries are structured around the knowledge that the spatial relation of the SCS critically espouses not only its geo-strategic significance in terms of natural resources endowment, but also the enduring maritime disputes within the region.     

The elephant in the room: US ballistic missile defence under Barack Obama

Conventional wisdom seems to hold that under Barack Obama, the US ballistic missile defence programme has been pushed aside to allow for a refreshed domestic and international agenda. Proponents point to Obama's campaign thinking and rhetoric, the ballistic missile defence (BMD) budget cuts, the decision to end the Third Site in Europe, and the reset relations with Russia through the New Strategic Arms Reduction Treaty (New START) as evidence that the programme has undergone a significant period of change, retraction and rationalisation. This article argues instead that BMD has not fallen from prominence and that there is a change in focus rather than retraction of its strategic goal. Consequently, BMD continues to grow in importance as a component of US national security strategy.
