 Despite the importance of his title, Thơ rarely appeared with Diệm in public and was a figurehead with little influence. The real power lay with Diệm's younger brothers, Nhu and Cẩn, who commanded private armies and secret police, as well as giving orders directly to ARVN generals. Nhu reportedly once ordered a bodyguard to slap Thơ because he felt Thơ had shown him a lack of respect. Diệm held Thơ in contempt and did not allow him to take part in major policy decisions, despite theoretically being the second most powerful man in the country. Thơ had a rapport with the military officers, having befriended Minh years earlier. He was regarded as a genial and affable administrator with a reputation for making compromises.
