Barack Obama’s failure in Egypt has nothing to do with Egypt itself descending to chaos. No American administration has been willing to call Hosni Mubarak a dictator, which he is. And no administration has sought to strong arm Mubarak into a succession plan devoid of kleptocratic relatives.
We cannot blame Barack Obama for Egypt collapsing in on itself.
We can however blame Barack Obama for failing to mitigate and control the impact of the collapse.
