A post-heroic military policy

The Cold War induced caution in nations that feared uncontrollable escalation. Now that confrontations are less likely to careen out of control, a new season of bellicosity is here. The U.S. military, trapped in a Cold War mindset, has failed to realize this. It is spending far too much on casualty-prone units in all the services, in an age when political opposition to casualties effectively makes these units unavailable for combat. The military should recalibrate its priorities and shift funds to weapons such as high-tech lasers, stealth aircraft;and cruise missiles that can make warfare less lethal for Americans.
