Abstract: Donald Trump’s presidency and its consequent policies have spurred a series of geopolitical developments upending America’s core beliefs about globalization. Trump’s unilateral disruptions on various occasions, turning America’s back on globalization, have impacted the global economy, security, trade, climate, and polity in almost equal measure. However, the most severe implications of the Trumpian retreat from globalization could be for Asian security, an area where the USA has commanded a dominant influence since the end of the Second World War. Even as a transactional foreign policy approach has started to flow from Washington, Asia’s notion of collective security under the US umbrella faces an uncertain future. This process has been hastened by China’s growing assertiveness in the Asia-Pacific, particularly in the South China Sea and the Indian Ocean Region (IOR). Full text available here.
