However, in practice, men often found ways to impart information, and their letters offer a powerful and highly personal insight into the experience of war. Receiving letters from family and friends was also vital to morale, keeping men and women connected to the homes they had left behind.

A little-known correspondence between Einstein and Freud reveals his thoughts on war. In this letter, Einstein puts forth the idea for a world government run by an intellectual elite. His goal in this letter was to get Freud’s insight into the psychologial matter of violence and how to solve it.

Einstein was a lifelong pacifist and believed that wars stood in the way of human progress. He believed that wars were the result of natural aggressive tendencies found within all organisms and that the aims and causes of war were simply justification for these tendencies.

Freud brings his theory back to the present predicament, proposing that there is only one certain way of ending war — establishing, by consensus, a centralized body of control that resolves all such conflicts of interest.

Eight Main Causes of War

• Economic Gain.
• Territorial Gain.
• Religion.
• Nationalism.
• Revenge.
• Civil War.
• Revolutionary War.
• Defensive War.

War is not necessary for society to progress, a civilized society progresses directly from new ideas and innovations. There is no doubt that war directly effects those on the front lines who are fighting for the cause. But whats more, it effects every loved one at home, waiting for their spouse or child to return home.

freedom: how war affects human lives. And every war will change people’s lives – it might give them freedom, keep them safe, hurt them or their family and friends, give them more money, give them less money, bring them power, take away their power.

The wars won’t end. They will just be frozen, the temperature of the conflict brought down through a succession of ceasefires. At some point in the future, these failed states might be brought back to life, perhaps when some of the trauma has healed or the infections of hatred have subsided.

War is a bad thing because it involves deliberately killing or injuring people, and this is a fundamental wrong – an abuse of the victims’ human rights.

War subverts democracy and promotes tyranny and fanaticism; kills and sickens and impoverishes people; ravages nature. War is a keystone problem, the eradication of which would make our other social problems much more tractable. Second, war is more readily solvable than many other human afflictions.

Despite its horrors, war has made our world less violent, finds Ian Morris, a Stanford professor of classics and of history. From Roman conquests to World Wars, Morris noticed a pattern: War improved the quality of life for both winner and loser, gradually making societies safer and richer.

Warfare is violence involving groups of animals: either group-on-group or group-on-individual attacks. Such “coalitionary violence” is rare in the animal kingdom, confined to a few social insects like ants, and social mammals such as wolves, hyenas and lions. The “war”, as she called it, went on for four years.

War always brings negative impacts on the economy, environment, and social behavior of the people. One of the major disadvantages of war is, it destroys the economy of the region. Today, the economic cost of the war is too high because of weapons and ammunition is very expensive.

Death, injury, sexual violence, malnutrition, illness, and disability are some of the most threatening physical consequences of war, while post-traumatic stress disorder (PTSD), depression, and anxiety are some of the emotional effects.

Long-term wise a war could rebuild the economy of a country. As you can see, there are many bad and good sides of war. Overall I think wars are bad, because all these positive things are still not worth of millions of lives. And the good sides are if you win the war but that is not 100% sure.

War destroys communities and families and often disrupts the development of the social and economic fabric of nations. The effects of war include long-term physical and psychological harm to children and adults, as well as reduction in material and human capital.

Having some weapons at hand will help in this situation. Keep all weapons in a safe place, away from children, and grab them quickly if you need them….Move to an area far from fighting if you can.

1. Try to find areas that aren’t near the main fighting.
2. There may be designated civilian safe zones set up.

The usual strategies suggested by political scientists and international relations experts to prevent war include arms control and diplomacy. Approaches to arms control and diplomacy vary in their actual and potential effectiveness.

Conflict causes disruption and destruction of many sorts, including that of a people’s identity. That can be especially true with armed conflict where cultural sites and monuments are at greater risk of being damaged, intentionally or otherwise.

People can inadvertently destroy cultural heritage for a second time when cleaning up conflict sites after a war ends, according to archaeologist Dr Margarete van Ess, who says that databases and education are the best basis for safeguarding sites for the future.

Not only does war cripple the economy and politics, but on a deeper level, it taints society and forever alters the cultural identity of those people. They are forced to migrate for the sake of their safety and a better future, carrying their culture with them, but in the process altering it.

Military activity has significant impacts on the environment. Not only can war be destructive to the socioenvironment, but military activities produce extensive amounts of greenhouse gases (that contribute to anthropogenic climate change), pollution, and cause resource depletion, among other environmental impacts.

The wars in Iraq, Afghanistan, and Pakistan have had a serious impact on the natural environments of these countries.

War is a development issue. War kills, and its consequences extend far beyond deaths in battle. Armed conflict often leads to forced migration, long-term refugee problems, and the destruction of infrastructure. Social, political, and economic institutions can be permanently damaged.

Putting aside the very real human cost, war has also serious economic costs – loss of buildings, infrastructure, a decline in the working population, uncertainty, rise in debt and disruption to normal economic activity.

Heightened military spending during conflict does create employment, additional economic activity and contributes to the development of new technologies which can then filter through into other industries. These are some of the often discussed positive benefits of heightened government spending on military outlays.

These are the companies profiting the most from war:

• General Dynamics. > Arm sales 2012: $20.9 billion. > Total sales 2012: $31.5 billion.
• Raytheon. > Arm sales 2012: $22.5 billion.
• BAE Systems. > Arm sales 2012: $26.9 billion.
• Boeing. > Arm sales 2012: $27.6 billion.
• Lockheed Martin. > Arm sales 2012: $36 billion.

Wars often lead to increases in production, tighter labor markets, and higher wages. The large twentieth century wars contributed to declining inequality, the growth of the welfare state, and the advance of civil rights in the United States.
