Costa Rica’s declaration of war against the so-called Axis countries (Germany, Italy and Japan), in the context of World War II, has been the subject of ignorance and even jokes. This book is a strong and clear reminder of the scope of that declaration. Gertrud Peters Solórzano analyzes this period through a vast documentary exploration, especially through the written press of that time. Although this book dates back to the last century, its theme is even more valid in light of current conflicts.
