“Funny. I can see no historical evidence that war does any good for anyone in a human kind of way. Tangibly, war is good, more land or more oil or more any other resource for the victor. And who cares what the defeated feels or now has to go through to just survive.And lets introduce democracy or shoot them. And none of it will come back and bite the victor in the back side.

Ya war is wonderful as long as there are young men to send off to be killed.”

I have to respectfully disagree with you. Some wars (not all) do have benefits for hummanity.
WWII: Liberation of Europe, end of the genocidal policies of Adolf Hitler, end of imperialist Japan and their atrocities on mainland asia (ie The Rape of Nanking)

Korean War: Protection of South Korea from the horrors of communist North Korea. In essence saving millions from tyranical subjugation.

American War for Independence (Revolutionary War) and the War of 1812: Resulted in the creation and defense of the United States, which I consider a good thing.

Siege of Vienna 1529: Defeat of the Ottoman empire and their muslim expansion into central Europe.

Battle of Poitiers/Tours 732ad: Stopped muslim expansion from recently conquered Spain. Again, I believe that this was a good thing for humanity.

Battle of Salamis: Stopped the Persian Empire and led to the Greek victory at Platea ushering in the golden age of Athens which gave us concepts like democracy and great thinkers like Socrates and Plato.

These are just a few examples of true Casus Belli and wars that led to the improvement of humanity. I also think that Iraq is a better place since the removal of Saddam Hussein, but as an Iraq War vet I know that I am biased.
