If you find the english translation difficult to read, try it in german...

That is an intellectual challenge!
Yes, it is a difficult read.
It takes a concentrated mind, you can hardly skip a word or a sentence without getting lost.
For an easier access to "On War" I would recommend:
"Clausewitz and Modern Strategy" by Michael I. Handel,
published by Frank Cass & Co Ltd, Torowa, NJ 07511, USA.
That is Clausewitz in a modern context, and perhaps easier for modern people to understand.
