1. Most wars are asymmetrical or irregular.2. In these wars, the guerrillas/irregulars/insurgents do not aim for military victory.3. You can not defeat these groups by killing lots of their members. In fact, they want you to do that.4. High-tech weaponry is mostly useless in these wars.5. “Hearts and minds,” meaning propaganda and morale, are more important than military superiority.6.
