«One
of the things that preceded the failure
of the nation - state
of Syria and the rise
of ISIS was the effect
of climate change and the mega-drought that affected that region, wiped
out farmers, drove people to cities, created a humanitarian crisis that created the symptoms — or rather the conditions
of extreme poverty — that has now led to the rise
of ISIL and this
extreme violence,» the former Maryland governor said, fielding a question about foreign policy from Bloomberg.
