Published in a now out-of-print English translation by Chronos Press (UK) in 1982, the "new" version has been thoroughly proofread and copy-edited, and so reads much better than the original translation. It has also been enriched by a series of reference notes.
This very important text is extremely relevant to current discussions and debates about September 11th, on-going "Global War on Terrorism," NATO's "Operation Gladio" and other subjects.
