"When you get into trouble 5,000 miles from home, you’ve got to have been looking for it."
Will Rogers was a humorist and comedian back in the early 20th century but I think this quote does describe most of the wars in the history of mankind. Why was the Vietnam War and the 2nd War in Iraq so unpopular by the end of the war? Because we had very little reason to be there in the first place. All of Vietnam became communist and America stayed exactly the same decades later. In Iraq we certainly made things worse, not better. Wars are caused by many reasons, either because of riches, racism, religion, or just petty reasons. How many men all over the world since the dawn of civilization died thinking they were heroes for a just cause, but in truth were nothing but the pawns of politicians? Humanity has evolved in many ways in a few hundred years, but we never figured out that maybe war is not always the answer.
