I believe it is a game they are playing,and actually on each other's side.
Controlled conflict brings about controlled change,and if they want the world to come together as one they have to have the conflict to make it happen.
WW1,League of Nations set up,WW2,United Nations set up,and it will continue like that until the world realizes it must come together as one and put aside their differences.
I believe America and Russia are working together,and democrat and republican,for it is the Hegel System in play to bring forth a better system of operation.
And they are cooperating more in the world than people realize,but they want them all to come together as one.
