Across the political spectrum, there is wide agreement that Asia should be at the center of US foreign policy. But this worldview, the Pivot to Asia announced by the Obama Administration in 2011, is a dramatic departure from the entire history of American grand strategy. Ten years on, we now have some perspective to evaluate it in depth. In The Lost Decade, Robert Blackwill and Richard Fontaine take this long view. They conclude that there are few successes to speak of, and that we lack a coherent approach to the Indo-Pacific region. They examine the Pivot through various lenses: situating it historically in the context of America's global foreign policy, revealing the inside story of how it came about, assessing the effort thus far, identifying the ramifications in other regions (namely Europe and the Middle East), and proposing a path forward.
