In “Can Intervention Work?” Rory Stewart, a British diplomat and politician, and Gerald Knaus, a professor and author, argue that in certain circumstances limited, but resourced interventions for a humanitarian mission can succeed. The authors co-wrote an introduction at a moment when the international communality was debating whether and how to intervene in Libya, and highlight the West's history of imperfect interventions. They quote Anthony Lake's policy, “to help other nation’s build themselves” as a guiding principal in foreign intervention. The authors are critical of the RAND Corporation report "Beginner’s Guide to Nation-Building" and argue every intervention situation is different based on the local political economy and there is not one universal approach that always works. The rest of the book is divided into two sections: first, Stewart reviews the international experience in Afghanistan since &lt;a href="September%2011%20attacks"&gt;9/11&lt;/a&gt; based on his experience and travel in the country, and second, Knaus provides a case study on the international intervention in Bosnia. Overall, the authors warn against “over-interventions” such as Iraq that were based on “exaggerated fears" and “irrational confidence” and often ignored “local tradition, identity, and history.” Stewart and Knaus advocate an intervention policy based on ““principled incrementalism” that invest time and resources in understanding local context and defining concrete goals.
