On behalf of the contributors, we offer this Volume in friendship, respect and admiration for Professor Yoram Dinstein. No-one familiar with his wide-ranging work in the field can feel anything but awe for his contribution to the clarifica- tion and development of international law. To us, Yoram has also been a selfless, albeit – as anyone who knows him well understands – demanding, mentor, one who has sharpened our understanding of, and ability to think critically about, the law. Along with many others, we have also benefited over the years from his eru- dition on a range of subjects well beyond international.
