They likely told Trump that the Iranians would support Trump and that Trump would be a hero.

Trump is extremely easy to manipulate. Tell Trump that his legacy will be great and he will listen to you over all of his advisors (NSA, CIA, etc. etc.). The intelligence agencies are useless because the narcissist only cares about himself.

It's been the same thing with every foreign affairs issue for over a decade now. Trump just agrees with the people who butter him up.
