The GWOT, since its conceptualization 13 years ago, in the aftermath of 9/11, is the gift that keeps on giving. And no gift is bigger than a Transformer Al-Qaeda on steroids ? bigger, brasher, and wealthier than anything Osama Bin Laden and Ayman al-Zawahiri had ever dreamt of; the IS (Islamic State, formerly known as ISIS) of Caliph Ibrahim, former Abu Bakr al-Baghdadi.
US President Barack Obama, before deploying his golf holidays in Martha's Vineyard, casually dropped that bombing the Caliph's goons in Iraq will take months. One may interpret it as another layer of the Obama administration's self-avowed "Don't Do Stupid Stuff" foreign policy doctrine, not so subtly mocked by prospective presidential candidate Hillary Clinton. Shock and Awe in 2003 destroyed the whole of Baghdad's infrastructure in only a few hours.
Obama also confirmed the US was showering Iraq again with humanitarian bombing "to protect American interests" (first and foremost) and, as an afterthought, "human rights in Iraq."
