'Nikolas Stürchler deserves not only the credit for having submitted the first comprehensive analysis on 'Art. 2 (4)'s blind spot', but also for having approached this subject matter in a well-balanced, historically informed and excellently written manner. The overall objective of his treatise is to both explore the legal meaning of the no-threat principle and to draw conclusions on how it operates in practice and it shall be stated right at the outset that Stürchler succeeds in achieving this aim. … Stürchler's book is an excellent piece of academic work which deserves wide readership, not only with a view to the detailed and standard-setting examination of State practice contained therein.'
