Book excerpt: Clear explanations of recent events in the new global War on Terror. The US is back at war. A new version of what was once known as George W. Bush's “global war on terror” has become the central component of American foreign policy. The US/NATO assault on Libya in 2011, thousands of troops on the ground in Iraq, plans to keep combat troops in Afghanistan, drone wars rising in Pakistan, Yemen, Somalia and elsewhere—and now new air wars are underway against ISIS and others in Iraq, Syria and perhaps beyond. In this newest addition to Interlink’s wide-ranging Understanding Global Issues series, Phyllis Bennis asks and answers the basic questions facing so many Americans: What is ISIS? Why are they so violent? Should Obama have kept troops in Iraq? Is ISIS the same as al-Qaeda? Can you really go to war against terror? How should the US respond to ISIS violence? What dangers lie ahead? Without jargon, in an easy-to-use Frequently Asked Questions format, Bennis sorts through the hype to get to the root of this newest edition of the continuing global war on terror.
