SYMBIOSIS is the most important psychoanalytic concept. It begins with the phantasy that one is "at one" with the mother: the illusion of no separation.
The fantasy then moves to other objects in "reality." 

The most important symbiotic object is "the country," symbolized by the flag. The photo above depicts the dynamic. Trump "in love" with the American flag. No separation between Trump and "America."

The infantile phantasy of oneness with nations is the source of world history. Where it begins. Human beings are unable to separate from their mother (countries). They die and kill for mother countries.

"Imagine there's no country" (from my colleague John Lennon).
