It’s interesting that you use cartoon caricatures of Trump, rather than actual videos, to prove your point. Political cartoons don’t capture the collective unconscious; they’re written by partisans. Trump’s a very typical SEE. Charismatic, often crass, knows how to play crowds, capable of going for the jugular.
An actual example of an infantile world leader might be Boris Johnson, who seems ILE to me. Trump likes popularity, but BoJo seems to want specifically to be admired for his intelligence and uniqueness. His media stunts show that he doesn’t mind being seem as bumbling or absentminded, but spontaneously reciting the Iliad is
stereotypical Alpha-infantile attention-seeking behavior to “prove” that he’s special and brilliant and all that.
Also, infantiles aren’t really “wrathful”, at least not for long, and especially not ILEs. ILEs at most punch a wall or something and then ruminate, or take off to get out of their heads. They don’t really intentionally take out their anger on people, and they don’t really like to think about or bring up their feelings, especially long after whatever incident set them off. They’d generally rather just not deal with a person or problem than start a fight with them. They don’t really have venom, and if they are upset, a homemade meal is much more likely to “pacify” them than shouting their praise, which just helps keep their egos at their preferred girth.
You seem to be taking the infantile analogy too far as well. Infantiles are like kids in some respects, e.g. in that they’re receptive to being told what to do in certain areas, or they’re receptive to praise, or they tend to be obedient to their partners in the way that children would be obedient to their parents, or they tend to be particularly curious and interested in new things. But it’s just an analogy.
