Well, it is on US military professional reading lists for the Services, academies and intelligence professionals, which should tell you something. I found it interesting.

It's worth the read to understand what the Chinese are reading.

That said, and not really important, is there is plenty of doubt Sun Tzu really existed.

The Art of War could just be a compilation of various writings from different authors. Who knows...

As CT '97 says, it is not a pleasure read, although it is a very short book and can be read quickly.

It does apply, however, to more than just military. I read it while serving and again when I bought a business. Valuable teachings in a lot of life.

I enjoyed it.

it was interesting and a good read to take up part of an evening. If you are military, just read it and get it out of the way. Flyboy hit it when its more of a broad stroke on things. Don't attack with the sun in your eye. make sure you have the high ground. don't outrun your supply line.

Sometimes the simple stuff can be clearly overlooked. It's just another tool in the toolbox, but it's nothing to dismiss either. We get the simple stuff wrong more often than we should.

For the OP - Jomini, Clausewitz, Thucydides, Sun Tzu all have their place...especially if you ever start to work beyond a tactical level of war.
