The South Atlantic and the Antarctic have drawn considerable attention from big powers, who are racing to strengthen their regional footprints and presence as the region opens up for navigation and other potential uses.

Despite very low tensions, the South Atlantic is a recurrent area of discussion in the UK given the territorial claim over the Falkland archipelago by Argentina. The UK’s commitment to defend its overseas territories, blending both soft and hard power, has larger strategic implications given the increasingly contested geopolitics of the South Atlantic. In this episode, host Neil Melvin is joined by Juan Pablo Toro of AthenaLab in Chile and Dr Carlos Solar, Senior Research Fellow at RUSI, to discuss the prospects of the South Atlantic and Antarctica becoming zones where geo-economic competition and militarisation risk destabilising the status quo.
