Is it that a genuine acknowledgement of the existence of a vast network of global garrisons would lead to uncomfortable conclusions about the imperial nature of this country? I'm not sure myself. That they remain largely surrounded by an accepted and acceptable silence, however, continues to be an American reality.
America's famed "containment policy" vis-à-vis the Soviet Union didn't just contain that superpower -- it contained us, too. With the Soviet Union gone, the U.S. military was freed from containment. There was nowhere it couldn't go and nothing it couldn't do -- or so the top officials of the Bush administration came into power thinking, even before 9/11.
While these efforts are all necessary to the ultimate destruction of IS, sadly it is far from sufficient. As the George W. Bush administration failed to ask and answer the crucial "what next" question of what to do once Saddam Hussein and his army were overwhelmed, the Obama White House is repeating this act of strategic ignorance.
