No offense, but why do we give hits to National Journal? ITs like watching MSNBC all day.
No offense taken. The answer to your question is “Know your enemy”.
The ancient Chinese warrior Sun Tzu taught his men to “know your enemy” before going into battle. For if “you know your enemy and know yourself,” he wrote, “you need not fear the result of a hundred battles.” But, Sun Tzu warned, “If you know yourself but not the enemy, for every victory gained you will also suffer a defeat.”
