   • 2014 November 17, Roger Cohen, “The horror! The horror! The trauma of ISIS [print version: International New York Times, 18 November 2014, p. 9]”, in The New York Times‎:

     What is unbearable, in fact, is the feeling, 13 years after 9/11, that America has been chasing its tail; that, in some whack-a-mole horror show, the quashing of a jihadi enclave here only spurs the sprouting of another there; that the ideology of Al Qaeda is still reverberating through a blocked Arab world whose Sunni-Shia balance (insofar as that went) was upended by the American invasion of Iraq.
