Sun Tzu's: 'The Art of War'; should be mandatory reading for all 'newbees'
Sun Tzu Art of War. Sun Tzu's Art of War has been a "best selling" book for 2,500 years. It was written during the warring states period of China around 500 B.C. when Chinese kingdoms fought each other on a frequent basis.
Sun Tzu was a genius. However - this is 2019, the battle is the whole world, not territorial, in just a regional sense. Striking regional 'assets' would be in order at some level, maybe?
