President Donald Trump loves to utilize nontraditional emissaries for foreign policy to help the conventional U.S. diplomats.

He leaned on his son-in-law, Jared Kushner, and Steve Witkoff, a real estate developer who had not had diplomatic experience prior to Trump’s second term, to seal the Israel-Hamas ceasefire, and now, with a renewed push to end the Russia-Ukraine war, his new unconventional diplomat is Army Secretary Dan Driscoll.
