One of the defining features of the Donald Trump presidency has been his disdain for traditional US security alliances. While Trump’s views on foreign affairs are in constant flux, one persistent theme has been his conviction that the United States reaps insufficient benefits from its role as a security protector of Europe. Adding to these uncertainties is the fact that Europe’s prominence in American grand strategy has been steadily eroding. As expressed by both Democrats and Republicans, vital US national interests today are, first and foremost, tied to developments in the Indo-Pacific. With all these internal and external pressures on multiple fronts, can NATO still be revamped in a manner to meet the challenges of today? Is America’s role as the lead security provider in Europe drawing to a close? The concluding chapter discusses the shadow of alliance abandonment and sketches out the possible future trajectories of US-Baltic relations.
