Literally, new Dark Ages for Syria. Compare Syria at Night, 2011 & 2015
Another sign of Syria's destruction:

Notice (in 2011) how bright the area around Damascus is. Note how Aleppo is brightly lit. In the southeast, look how the Euphrates River Valley is lit up at night.

In 2015, the Euphrates and Aleppo have gone completely dark, while Damascus is still powered up but much less so than in 2011. Literally new Dark Ages for Syria.
Obama failed to improve anything in Syria - can Putin turn the Islamic Caliphate out and put the lights back on? I doubt it.
If I'm interpreting end times Bible prophecy (and I am) perhaps Egypt's Sisi is the King of the South; Putin is the King of the North, and Obama is, well you can guess - or read:
