Army Chief of Staff Gen. Mark A. Milley is a firm believer that a strong military is key in a whole-of-government approach to national security issues.
Still, he cautions, there are Americans who believe some myths about the military.
Here are his four "Myths of War:"
"War takes on a life of its own," Milley said. "It zigs and zags. More often than not, war is much longer, much more expensive, much bloodier, much more horrific than anyone thought at the beginning. It is important that the decision-makers assess the use of force and apply the logic we've learned over the years. War should always be the last resort."
"Armies or navies or air forces don't go to war. Nations go to war," Milley said.
