America and the 'forever war'

Anyone born in the US since September 11 has lived an entire lifetime in a nation at war. Presidents Bush, Obama and Trump have warned of threats from overseas -- but allies as well as enemies feel the real threat is America's unparalleled power. The total cost is up to $5.6 trillion, but less than one percent of the population has served -- and without shared sacrifice, foreign battlefields seem far away. Now the so-called "war on terror" is coming home, as Congress encourages local police to adopt military strategies and equipment designed for combat. In the name of ensuring freedom abroad, are we in danger of losing freedom at home? In December of the year 2000, this program went on the air. Less than a year later, everything changed.
