Demoralization is, in a context of warfare, national security, and law enforcement, a process in psychological warfare with the objective to erode morale among enemy combatants and/or noncombatants. That can encourage them to retreat, surrender, or defect rather than defeating them in combat.
Demoralization methods are military tactics such as hit-and-run attacks, such as snipers disturbing the enemy with less-lethal weapons and incapacitating agents, and intimidation such as display of force concentration. Some methods on the strategic scale are commerce raiding, strategic bombing, static operations such as sieges and naval blockades, and propaganda.
Morale is often perceived as a necessary precursor to success in international relations. Success most often goes to those who believe in their cause, as they more easily maintain a positive outlook that helps them work harder for it. High morale can directly contribute to "an economy of food, textiles, fuel, and other commodities, and to stimulate recruiting, employment in war industries, service in relief work, and the purchase of bonds". Writing in 1965, French philosopher and sociologist Jacques Ellul described the importance of morale in modern society by saying:
The modern citizen is asked to participate in wars such as have never been seen before. All men must prepare for war, and for a dreadful type of war at that – dreadful because of its duration, the immensity of its operations, its tremendous losses, and the atrocity of the means employed. Moreover, participation in war is no longer limited to the duration of the war itself; there is the period of preparation for war, which becomes more and more intense and costly. Then there is the period in which to repair the ravages of war. People really live in a permanent atmosphere of war, and a superhuman war in every respect. Nowadays everybody is affected by war; everybody lives under its threat...The more demanded of man, the more powerful must be those motivations.
