In general, war is a very controversial and complicated series of events, but war still is a very sad last resort for humans. The statistics of how bloody and dreadful war can show the gruesomeness of this act. In armed conflicts since 1945, ninety percent of casualties have been civilians compared to fifty percent in the Second World War and ten percent in the First. The planning and execution of war remains controlled by men, but women and children are the main victims of violence in war. 160 million people died in wars during the 20th century.

The means used have to lead to the end of war. These beliefs and statements have come from a variety of sources that comes all the way back to Augustine of Hippo.

Of course, he wanted violence to be prevented as long as possible, but he still thought God gave them the sword for a reason. He wanted Christians to be able to protect peace and fight off the wicked. Augustine even went as far to say that it would be a sin not to protect oneself when violence is the only answer.

Born nine hundred years after Augustine, Thomas Aquinas was an extremely influential philosopher and theologian. Using Augustine’s pass statements, he stated three of the six criteria. They stated: a war must be waged for a good purpose, not self-gain, just war must be properly controlled by the state, and peace must be a central motive in war.
The School of Salamanca wished to expand on Thomas’ beliefs and statements. They
