Everything Old Is New Again

Hoping to prevent a replay of last months rebel siege, the Chadian government is building a moat around the capital city N'Djamena.  

And while the government of Chad is building moats and chopping down trees to protect their citizens, the world is busy taking pictures of their fleeing compatriots from the relatively safe distance of 200 miles above the earth.  These are images (pdf) from UNOSAT (via War and Health) taken on Feb. 4th during the mass exodus from the capital, and you can't deny their power.  Satellites and moats.  Moats and satellites.  Its a crazy world.
