The war

It seems there might be a typo in your question. If you're asking why people live through war, it's because war is a complex social, political, and economic phenomenon that arises due to a variety of factors including conflicts over resources, territory, ideological differences, power struggles, and more. Civilians caught in conflict zones often have no choice but to endure the hardships imposed by these circumstances.

However, if you're asking why people wage war, the reasons are multifaceted:

1. **Resource Conflicts:** Wars have been fought over access to resources like land, water, and more recently, oil. These are critical for economic development and can become sources of conflict between nations or within nations.

2. **Political Power and Control:** The desire to gain, maintain, or expand power can lead governments or groups to engage in war. This includes civil wars where factions within the same country vie for control.

3. **Territorial Disputes:** Disagreements over the ownership of land have been a common cause of war throughout history. Nations or groups may fight to claim territory or defend their land from being taken.

4. **Ideological Differences:** Conflicts often arise from deep-seated ideological differences, whether they be political (e.g., democracy vs. authoritarianism), religious, or social (e.g., issues of equality and rights).

5. **Nationalism:** Intense national pride and the belief in the superiority of one's nation or ethnic group can lead to conflicts with perceived rivals or minorities within a country.

6. **Defensive Purposes:** Sometimes, wars are fought out of necessity to defend against aggression or to prevent potential threats from gaining strength.

7. **Economic Gain:** Economic motives can drive wars, whether it's to control valuable resources or to stimulate an economy through wartime production.

8. **Revenge or Retribution:** Historical grievances and the desire for revenge can trigger conflicts, especially if previous wars or wrongs are unresolved.

9. **Social and Political Instability:** Internal unrest, economic decline, and loss of confidence in institutions can make nations or groups more likely to engage in conflict as a way to divert attention from domestic issues or rally people around a common enemy.

Understanding why people engage in war requires examining a wide array of factors, including historical contexts, human psychology, and the complex interplay between different socio-political and economic forces. It's also important to note that the reasons for war can vary widely from one conflict to another, and often, multiple factors converge to spark or sustain wars.

A tank is an armoured fighting vehicle intended as a primary offensive weapon in front-line ground combat. Tank designs are a balance of heavy firepower, strong armour, and battlefield mobility provided by tracks and a powerful engine; their main armament is often mounted within a turret. They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat.

A main battle tank (MBT), also known as a battle tank or universal tank,[1] is a tank that fills the role of armour-protected direct fire and maneuver in many modern armies. Cold War-era development of more powerful engines, better suspension systems and lighter composite armour allowed for the design of a tank that had the firepower of a super-heavy tank, the armour protection of a heavy tank, and the mobility of a light tank, in a package with the weight of a medium tank. The first designated MBT was the British Chieftain tank, which during its development in the 1950s was re-designed as an MBT.[a] Throughout the 1960s and 1970s, the MBT replaced almost all other types of tanks, leaving only some specialist roles to be filled by lighter designs or other types of armoured fighting vehicles.A main battle tank (MBT), also known as a battle tank or universal tank,[1] is a tank that fills the role of armour-protected direct fire and maneuver in many modern armies.
