The news that the United States had killed 150 unnamed individuals in a country halfway around the world with which it is not at war generated barely a ripple of attention, much less any protest, here at home. Remote killing outside of war zones, it seems, has become business as usual. This is a remarkable development, all the more noteworthy in that it has emerged under Barack Obama, who came to office as an antiwar president, so much so that he may be the only person to win the Nobel Peace Prize based on wishful thinking.
