Perpetual war

Perpetual war, endless war, or a forever war, is a lasting state of war with no clear conditions that would lead to its conclusion.^{[citation needed]} These wars are situations of ongoing tension that may escalate at any moment, similar to the Cold War. From the late 20th century, the concepts have been used to critique the United States Armed Forces interventions in foreign nations and the military–industrial complex such as the Vietnam War and the Soviet-Afghan War, or wars with ambiguous enemies such as the war on terror or war on drugs.
