War, as defined by Merriam-Webster as ‘open and declared
armed hostile conflict between states or nations’, is ugly and
devastating both economically and in terms of the cost of
human life. War is also, sadly, persistent and prevalent. As
Chinese military strategist Sun Tzu stated in his book “The Art
of War”, from around 500 BC, “War causes inflation and
makes people poor,” especially referring to periods of
prolonged war. Military strategists still learn from his book
today.
While there are certainly conflicts which have caused more
death than some of the listings below – such as the Taiping
Rebellion of China that left 20 million dead, the An-Lushan
Rebellion that killed 13 million, and the Mongol Conquests
that killed 40+ million – it has proven impossible to accurately
deduce the costs of these wars. Here, we’ve taken a look at the
tragic conflicts which were both the deadliest and costliest,
based on empirical data that draws on both the financial drain
and the death toll of more modern wars and conflicts.

9. Syrian Civil War – (Cost: $25 billion)
(Death Toll: 191,000)
Syria is the latest Middle Eastern country that everyone is
following in the media and at home, and for good reason. With
ISIS and the United States’ recent decision to bomb the
terrorist group with help from five Arab factions, and the three
year civil war, things have been in utter turmoil in Syria for
quite some time.
On March 15, 2011, Syrian protesters rallied against the regime
of President Bashar Assad. It started as a peaceful uprising
until Assad cracked down with vicious force and found the
protestors retaliating. The uprising became an armed
insurgency by July. Three years on, neighboring nations have
come in to contribute weapons, fighters, funding, and
assistance to both sides. Russia, Iran and Lebanese militia
Hezbollah back the government, while the Western powers, the
Gulf states and Turkey support the various rebels. As the civil
war has displaced 2.5 million people and killed another
191,000, this is a devastating and costly war both in terms of
finances and lives lost.

*dusts seat*

8. American Civil War – (Cost: $84
billion) (Death Toll: 750,000). For 110 years, the American Civil War’s death toll stood at an
exact 618,222 men killed – by far the greatest toll of any war in
American history. A 2012 census study that has gained wide
scholarly acceptance raised that number by 20%, to 750,000,
further elevating the significance and devastation of the
already epic war.
The war between the northern Union and the southern
Confederacy was, on the surface, a conflict over abolishing
slavery, while the real war was over political and monetary
control. The bloody 4-year war became an expensive mass of
politics and ideology that often had family members fighting
against each other. This time of conflict also birthed some of
the 19th century’s most influential Americans, such as Ulysses
S. Grant, Robert E. Lee, William T. Sherman, and many more.

7. Iraq/Afghanistan/Pakistan War –
(Cost: $3.4+ trillion) (Death Toll: 300 –
350,000). Recent studies show that the cost of the War on Terror,
including both the Iraq and Afghanistan wars, are the most
expensive wars in human history. The direct costs have been
estimated at between $3 and $4 trillion dollars, while veteran
benefits and other expenses will in the end raise that cost to $6
trillion, or the equivalent of $75,000 for every American
household.
Though the Iraq war began under what are generally accepted
to have been false pretenses (that they possessed nuclear
warheads), the outcome of the war led to the overthrow and
execution of Saddam Hussein. Still, the war is largely seen as a
failure since the escalation of insurgency spilled over into the
Syrian Civil War once Americans departed, and many argue
that the country is worse off than when the US went in. The
official death toll of the bloody conflicts varies greatly, but
there is no doubting that this conflict is one of the most brutal
in recent history.

Nice topic this is...






War never leave where it found a nation..

6. Soviet War in Afghanistan – (Cost:
$106.3 billion) (Death Toll: 958,000 – 1.6
million). The Soviet war in Afghanistan lasted 9 long years, from
Christmas Eve 1979 to February 15, 1989. It was part of the
Cold War and was fought between Soviet-led Afghan forces
and the multinational insurgent group Mujahideen. The
Mujahideen received military training from Pakistan and
China, as well as weapons and billions of dollars from the US,
UK, Saudi Arabia, and Iran.
The Afghan government secured a treaty in December 1978
that allowed them to call on Soviet forces to fight against
Mujahideen rebels. Foreign ministers from 34 Islamic nations
condemned the Soviet’s intervention, calling for their
immediate withdrawal. This would not happen until 1987, after
Mikhail Gorbachev came on to the scene and introduced his
‘new thinking’ on domestic and foreign policy. The conflict
has sometimes been referred to as the “Soviet Union’s Vietnam
War,” and while the military death toll was large with 108,000
killed between the forces, the bigger tragedy was the death of
between 850,000 and 1.5 million civilians.

5. Iran-Iraq/Persian Gulf War – (Cost:
$109 billion) (Death Toll: 1 million). The Gulf War, codenamed Operation Desert Shield and then
Operation Desert Storm, was a war waged by a coalition of 34
nations against Iraq in response to Saddam Hussein’s invasion
and annexation of Kuwait in 1990. The war was one of the first
to receive around-the-clock TV coverage, and cost a huge $109
billion in just 6 months.
While the death toll was not very high in the Persian Gulf War,
if you consider the 8-year Iran-Iraq War from 1980 to 1988
that led up to the Gulf War, you have the 20th century’s
longest conventional war, and a very bloody one, resulting in
over 1 million deaths. Iran faced an economic loss of $627
billion after the Iran-Iraq conflict, while Iraq faced a $561
billion loss.

4. Korean War – (Cost: $364 billion)
(Death Toll: 1.2 million). The Korean War was waged between UN and US-backed South
Korea against China-backed North Korea, also assisted by the
Soviet Union. The war arose after the division of Korea at the
end of World War II and the tensions of the Cold War that
developed. Korea was ruled by Japan from 1910 until the end
of the war. In August 1945, the Soviet Union declared war on
Japan, and agreed with the US to occupy Korea north of the
38th parallel. US forces occupied the south, and both
governments claimed to be legitimate governments of Korea,
with neither side agreeing on a permanent border.
The conflict escalated into open warfare in 1950. The result
ended in an indecisive victory for either group, though the
death toll and monetary cost was monstrous. Over 500,000
fighters died directly from the 3-year war, while many more
civilians were massacred on both sides. The war has been seen
as a civil war and a proxy conflict in the Cold War between the
US and the Soviet Union.

3. Vietnam War – (Cost: $788.5 billion)
(Death Toll: 790,000 – 1.14 million). The Vietnam War will always be seen as the war that America
lost, and also as one of the messiest wars from start to finish.
Fought from 1965 to 1975, the conflict scarred the American
and Vietnamese nations, both physically and mentally. The US
pulled out of the country just prior to being destroyed.
While the war saw widespread US public support in the
beginning years, by the time American veterans returned home
from the horrible conflict they were met with contempt and
non-existent support. The economic toll was huge, but the loss
of life was far greater. While the US lost 58,220 soldiers, and
had 303,644 wounded, the Vietnamese people faced a far
greater onslaught of death with hundreds of thousands of
military men and civilians dead by the end of the conflict.

2. World War I – (Cost: $357 billion)
(Death Toll: 17 million). One of the deadliest conflicts in history, the Great War began
in 1914 with the US joining in 1917. What started as a
conventional trench war saw unprecedented technological
advances by the end of the conflict in 1918, helping to
exacerbating the casualty rate to an unprecedented 10 million
combatants and 7 million civilians during the 4-year war.
The immediate trigger for the war was the assassination of
Archduke Franz Ferdinand of Austria on June 28, 1914. He was
the heir to the Austro-Hungarian throne, and his death set off a
diplomatic crisis between them and the Kingdom of Serbia.
Soon, the war spread worldwide, driving in all of the world’s
economic powers, which were divided into two opposing
alliances: the Allied Powers of Britain, France, and others, and
the Central Powers of Germany, Bulgaria, Austria-Hungary,
and Turkey. Ultimately, more than 70 million military
personnel were mobilized in one of the largest wars in history.

We dont need them wars, thats why we should say NO to APC

Strongly doubt these figures especially the casualties

1. World War II – (Cost: $4.1 trillion)
(Death Toll: 72 million). World War II was the deadliest conflict in human history,
resulting in the deaths of between 50 and 85 million people. It
pitted the Allies against the Axis, included all of the great
military powers, and was marked by the mass deaths of
civilians, including the Holocaust, the atomic bombings of
Hiroshima and Nagasaki, and more.
The Empire of Japan was already at war with the Republic of
China in 1937, but the world war is generally regarded as
beginning with the invasion of Poland by Germany on
September 1, 1939. The December 1941 Japanese attack on
Pearl Harbor brought the United States into the war. WWII is
probably the most catastrophic war in world history, both
economically, and especially as the death toll showed the
destruction mankind is capable of.
