Brink of WW3?
How and in what way?
Most countries are backed in the UN.
Even Russia wouldn't dare to even go against it because most of the countries would easily switch to defend one another.
America has been part of NATO. Russia disbanded warsaw a long time ago.
In order for it to even consider a world war, it has to involve almost every nation of the world. This would probably be named Cold War part 2 more than anything else.
Countries are like kids -- they fight each other because someone threw a rock at somebody.
They use the small things as an excuse to go to war, therefore gaining resources such as oil + territory.
They tell the public that they are in war because of other reasons, although it is pretty obvious why they're there.
Us, the general population, are oblivious to what is right in front of us and continue to believe their lies.
