The Tree that Almost Started a War 

In 1976, a poplar tree in the demilitarized zone between North and South Korea was getting a little too big. So the United States and South Korea decided to send some men to trim the tree in what should have been a routine operation. I won't spoil what happened, but let's just say it's now known as the Korean axe murder incident. So the United Nations Command launched an extensive military operation to cut down this tree in a show of force. Officially known as Operation Paul Bunyan, hundreds of soldiers marched into the DMZ to cut a tree, assisted by jets, bombers, and an aircraft carrier. Hopefully that'll teach the North Koreans to let us do our tree-trimming in peace!
