The world today seems to be plagued with conflict allover the place that can all escalate fairly quickly.
There is the looming escalation in the Middle East, a possible escalation in Korea, wide spread terror in Africa, Russia looking to expand their influence in Eastern Europe, etc. etc.
If this isn't enough, there are warnings for a while now about a possible major financial crisis this year that could bankrupt countries like China and Russia and let's be honest, Europe and US would suffer enormously from this as well.
Then there are internal struggles in the West, like the refugee crisis in Europe, the rise of right-wing nationalism in many EU countries, there could be racial conflicts in the US, wealth inequality could spark civil wars, etc. etc.
So yeah, not too much to be happy about. But the question is: how close do YOU think we are to a possible world wide conflict, or a WW3?
