It is an excellent account of Lithuanian foreign policy between the world wars: its struggle with Poland regarding Vilnius/Wilno Region, with Germany regarding Klaipeda/Memel Region, its balancing act between Soviet Russia, Nazi Germany, and Western Europe. It all ended badly, but the book analyzes how a small nation attempted to prevent the unpreventable disasters by leveraging conflicts between the nations. As it is said, where two fight, the third wins. Lithuania hoped to be that "third." After reading the book you not only know what happened, but also start appreciating the struggles, complexities, and general mess in interwar Europe. You start to understand the subtle differences and why they were so important.
The topic is extremely complex, but the authors make it an easy and captivating read. Events are not isolated in Lithuanian world: there is always a glimpse of what world or European events caused this or that event. The book captures just the right balance between details and general overview: just enough details to convey the complexity of issues, and not enough to overwhelm. Issues are discussed from several positions and views without endorsing any of them. The authors clearly done their research and know their stuff.
Highly recommended.
