Obama ... is stepping once again - and with understandably great reluctance - into the chaos
of an entire civilization that has broken down. Arab civilization, such as we knew it, is all but
gone. The Arab world today is more violent, unstable, fragmented and driven by extremism -
the extremism of the rulers and those in opposition-than at any time since the collapse of the
Ottoman Empire a century ago.
