I watched a documentary and this is what popped in to my mind. It is more or less established that ****** was ENFj and Stalin was ISTj. Which is funny because it would make them duals. Initially they did have positive relations and mutual non-aggression pact and all that but in the end ****** got too confused and decided that he needs to attack Stalin too and this aggression went really personal and to the point where ****** seriously wanted to capture Stalin's favorite city i.e. Stalingrad. Battle of Stalingrad was eventually the culmination point of the whole war from which on Stalin more or less kicked ******'s butt.
So what I was thinking...does this reflect the general nature of ENFj / ISTj duality? First they make a non-aggression pact and pretend to be friends. ENFj however doesn't respect the ISTj much and eventually will backstab and go all out on the ISTj. After a furious battle the ISTj will pwn the ENFj. Perhaps this is true for their erotic games too. Hah.
