As the United States’ commitment to global leadership and principles grows ever more uncertain under President Donald Trump, Japan finds itself with little choice but to look beyond its closest ally to ensure economic and military security, according to analyst Ian Bremmer, the head of political risk consultancy Eurasia Group.

Bremmer earned his doctorate in political science from Stanford University and is the author of a number of books on foreign affairs, as well as a columnist and editor-at-large for Time Magazine. His most recent book, released in April of 2018, is titled “Us vs. Them: The Failure of Globalism.”

He sees seismic shifts in U.S. and other Western countries’ foreign policies, which have significant implications for Japan.
