We haven’t had anything close to the present state of affairs since WWII. The Cuban Missile Crisis could have caused a WW, but that was a singular incident. What is happening now in the ME, Africa, Ukraine, Russia is something all together different.....
The present state of affairs was brought about by Obama. But, even so, it’s still not a World War. And my prediction is that when Obama leaves office, it still won’t be a World War ... and then the next President can start acting like a real President should and we’ll try to undo all the damage Obama has caused.
