President Donald Trump wants to project a certain image on the global stage, and some world leaders have learned how to use that to their advantage, according to one expert. Trump wants to appear as a ruthless leader on par with strongmen like Russia's Vladimir Putin or China's Xi Jinping, according to Fiona Hill, Trump's Russia advisor during the first administration. Hill said during an interview on the "The Court of History" podcast on Monday that Trump's desire to be seen in this light gives world leaders a psychological advantage when they interact with the U.S. president, because they have turned that desire for adoration into currency. "Putin, I think, understands it perfectly," Hill said. "Because if you look at Putin, he rations out his access to him for Trump. He kind of dangles things out of there, plays just hard to get all the time because he knows that Trump, more than anything else, wants his adulation and respect, and Putin's just not going to give that because that's currency. That's extraordinarily valuable."Hill recalled being on phone calls between Trump and Putin and noticing that the Russian leader had "so much of an advantage" against Trump. It also appears that "he knows this" as well, Hill said. "He is not that ruthless," she continued, referring to Trump. "He wants to be treated as if he is, but he's just not that ruthless. And that's why he is intimidated by Putin, because he wants everybody else to think of the United States in that same manner. He doesn't want to be benign and benevolent. If he can't be respected, he wants to be feared. He doesn't want to be made fun of or to become a meme."
