No, regional wars DO NOT BECOME World Wars. We’ve had so many regional wars (so many I can’t count them) since World War II ... and STILL we have not had World War III
I defer to your knowledge and wisdom.
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.....
