The moral status of spying and covert activity - a difficult subject that deserves to be discussed in a separate thread. I don't think that such activity is necessarily cowardly or immoral; in fact some of the cativities by the French Resistance required courage of the very highest kind.
What I want to say it is Miss Cavell ´s execution was moral and legal according with the Laws of Wars.. as Mata - Hari. Our Century is coward.. very much...and amoral... I don´t know if we are cowards because we are amoral or we are amoral because we are cowards...but we are both!
In 1915 people believed what they were doing (both Miss Cavell as the German Generals).. courage people believed in their causes... today nobody believe in nothing...We have plumbed such depths than a little dwarf as ISI or Al Qaeda... looks to us as a Giant!
