This is a desert country, bankrupt for 20 years, and dependent on foreign dollar aid to buy food.
Syria is a vicious civil war, with a minority governing sect fighting for its life against an abused majority.
After 7 decades of democratic progress in the EU, there are bound to be push backs. Is the Brexit insanity related to climate change?
Well-managed China will leverage Green Tech as an economic opportunity. Mis-managed countries will sink lower. Sad but true.
Interesting point about China, do they have a refugee crisis? I suppose being seen as an oppressive regime not scared to shoot at people has its advantages.

So, break a nation? Climate change broke a few already.
The EU governments are already making it hard for refugees to cross the Medditerranean (financing the Libyan Coast Guard to stop "smugglers", as well as camps in Turkey), although all the Neo-Nazis still scream about it, I can imagine that when more right wing governments get voted to "represent" the populace, they'll take even more drastic measures (even more than the Italian government refusing docking rights to ships which rescue refugees).
