Diego's public speech lasted only thirty minutes; Lance could tell he might have made some cuts to the script.
Some places clearly had a disjointed feeling, especially focused on the parts praising the people.
Lance didn't have much time or many opportunities dealing with Diego, but he could feel this was a typical president, still holding onto the "old slave owner mentality," a ruler.
He regarded the people of this country as his domesticated slaves, so when asked to praise the people, he felt uncomfortable.
It's like those slave owners before the Federation liberation movement; asking them to say, "As long as you work hard, I will free you and give you a piece of land, so you can live a peaceful and prosperous life," is worse than pulling out a gun and shooting them a couple of times so they can at least die comfortably.
