Spheres of influence - The notion that does not exist?

The notion is denounced but persists in political discourse.

The Monroe Doctrine and “Spheres of Influence” are mutually dependent notions, 

Modern politics cannot be pursued without them.

The messianic search for sovereignty untarnished
by the concept of “spheres of influence” is
counterbalanced in realpolitik by negotiated
settlements (often secret) aimed at safeguarding the
status quo through “fair” partition of spheres of
influence.
