casus belli

 

Casus belli is a modern Latin language expression meaning the justification for acts of war. Casus means "incident", "rupture" or indeed "case", while belli means "of war".

It is often misspelled and mispronounced as "causus belli" since this resembles the English "cause" (and a different Latin word, causa {cause}). "Casus belli" is also pronounced this way because the term is used with the meaning of "cause for war", instead of "case of war" (notice that "case" comes from Latin "casus").

Despite the apparent age that the use of Latin confers on it, the term did not come into wide usage until the late nineteenth century with the rise of the political doctrine of jus ad bellum or "just war theory".^{[citation needed]} Informal usage varies beyond its technical definition to refer to any "just cause" a nation may claim for entering into a conflict. As such, it has been used both retroactively to describe situations in history before the term came into wide usage and in the present day when describing situations when war has not been formally declared.

Formally, a government would lay out its reasons for going to war, as well as its intentions in prosecuting it and the steps that might be taken to avert it. In so doing, the government would attempt to demonstrate that it was going to war only as a last resort (ultima Ratio) and that it in fact possessed "just cause" for doing so. Effectively international law today only allows two situations as legal cause to go to war. Either out of self-defense or sanctioned by the UN. Any war for another casus belli is considered illegal and as such a war crime.

Proschema (plural proschemata) is the Greek equivalent term. These stated reasons may or may not be the actual reason for waging the war (prophases). The term was first popularized by Thucydides in his History of the Peloponnesian War, who identified fear, honor, and interest as the three primary real reasons that wars are waged, while proschemata commonly play up nationalism or fearmongering (as opposed to rational or reasonable fears).

Reasons for use

Countries generally need a justification of some sort for attacking another country. The justification may be needed principally to galvanize support for the war internally (since citizens may not be happy about being expected to fight and die in a dubious cause), or else to galvanize the support of potential allies and reduce or avoid international sanctions or possible intervention. This has been the case for much of world history and is still the case today.

In the post World War Two era, the UN Charter has made it illegal for signatory countries to engage in war except as a means of defending themselves against aggression, or unless the UN as a body has given prior approval to the operation. The UN also reserves the right to intervene against non-signatory countries which embark on wars of aggression. In effect, this means that countries in the modern era must have a plausible casus belli for initiating military action, or risk possible UN sanctions or intervention.

Historical examples

Spanish-American War

The US navy ship USS Maine sank in the Havana Harbor from an explosion whose cause remains controversial. Critics such as Gore Vidal have claimed that the explosion was a purposeful act to create a phony casus belli for the US to attack the Spanish. This gave the United States the political cover to have an excuse to attack Spain triggering the Spanish-American War because the US government accused the Spaniards of being responsible for the explosion^{[citation needed]}.

World War I

A political assassination provided the trigger that led to the outbreak of World War I. The assassination in June 1914 of Archduke Franz Ferdinand of Austria at Sarajevo in Austria-Hungary by Gavrilo Princip, a Yugoslav nationalist from Bosnia, Austrian subject and member of Young Bosnia, was used by Austria-Hungary as a casus belli for declaring war on Serbia.

The Russian Empire started to mobilise its troops in defence of its ally Serbia, which resulted in the German Empire declaring war on Russia in support of its ally Austria-Hungary. Very quickly, after the involvement of France, the Ottoman Empire and the British Empire, five of the six great European powers became involved in the first European general war since the Napoleonic Wars. (see Causes of World War I)

World War II

In his autobiography Mein Kampf, Adolf Hitler had advocated in the 1920's a policy of lebensraum ("living space") for the German people, which in practical terms meant German territorial expansion into Eastern Europe.

In August 1939, in order to implement the first phase of this policy, Germany's Nazi government under Hitler's leadership staged the Gleiwitz incident, which was used as a casus belli for the invasion of Poland the following September. Since Poland's allies Britain and France honoured their alliance and subsequently declared war on Germany, the invasion of Poland marks the start of World War II.

In 1941, acting once again in accordance with the policy of lebensraum, Nazi Germany invaded the Soviet Union, using the casus belli of pre-emptive war to justify the act of aggression.

The Soviet Union also employed a manufactured casus belli during World War II. In November 1939, shortly after the outbreak of hostilities between Germany, Britain and France, the Soviet Union staged the shelling of the Russian village of Mainila, which it blamed on the Finns. This manufactured incident was then used as a casus belli for the invasion of Finland. In 1998, Russian President Boris Yeltsin admitted that the invasion had in fact constituted a Soviet war of aggression.

Additionally, some sources theorize that the US government had prior warning of the impending Japanese attack on Pearl Harbor, but chose to ignore it in order to shock the country out of its prevailing mood of isolationism. By allowing the Japanese "stab in the back" to take place, this theory effectively contends, the US administration would be handed the strongest possible casus belli which would ensure the full and undivided support of the American populace for the coming war effort.

Six-Day War

A casus belli played a prominent role during the Six-Day War of 1967. The Israeli government had a short list of casus belli, acts that it would consider provocations justifying armed retaliation. The most important was a blockade of the Straits of Tiran leading into Eilat, Israel's only port to the Red Sea, through which Israel received much of its oil. After several border incidents between Israel and Egypt's allies Syria and Jordan, Egypt expelled UNEF peacekeepers from the Sinai Peninsula, established a military presence at Sharm el-Sheikh, and announced a blockade of the straits, prompting Israel to cite its casus belli in opening hostilities against Egypt.

Vietnam War

Some historians have suggested that the Gulf of Tonkin Incident was a manufactured pretext for the Vietnam War. North Vietnamese Naval officials have publicly stated that the USS Maddox was never fired on by North Vietnamese naval forces^[1][2].

Israeli Invasion of Lebanon

The casus belli cited by Israel for its June 1982 invasion of Lebanon was the attempted assassination of the Israeli Ambassador in London, which the Israeli government blamed on the PLO (although the attempt had actually been made by the PNLM, a Palestinian splinter group implacably opposed to the PLO).^[3] In reality however, the invasion had long been planned by the Israelis,^[4] who were concerned about the growing power of the PLO in Lebanon.

Turkey and Greece

In 1995, the Turkish parliament issued a casus belli against Greece in reaction to an enacted extension of Greek territorial waters from 6 to  nautical miles ( km) from the coast.^{[citation needed]} Turkey has not removed this casus belli despite initiation of preliminary negotiations in order for it to join the European Union.^{[citation needed]}

War on Terror

The casus belli for the Bush administration's conceptual War on Terror, which resulted in the 2001 Afghan war and the 2003 Iraq war, was the September 11, 2001 attacks on the World Trade Center in New York City, The Pentagon in Arlington, Virginia and the apparently intended attack on the United States Capitol in Washington, D.C..

2003 Invasion of Iraq

The United States' stated casus belli for it's 2003 invasion of Iraq was Saddam Hussein's non-compliance with the terms of cease fire for the 1990 - 1991 gulf war.

Cited by the Bush Administration was Saddam Hussein's weapons of mass destruction (WMD) program. The administration stated that Iraq had not conformed with its obligation to disarm under past UN Resolutions, and that Saddam Hussein was actively attempting to acquire a nuclear weapons capability as well as enhance an existing arsenal of chemical and biological weapons. Secretary of State Colin Powell addressed a plenary session of the United Nations Security Council on February 5, 2003 citing these reasons as justification for military action.[1]

Subsequent to the invasion reports established that although Saddam Hussein had intended to resume WMD production once the gulf war sanctions were lifted, no significant WMD stockpiles existed at the time of the invasion. [2]
