Let's look at it this way shall we.
The former king abdicated his throne and announced that the hero that the kingdom summoned will become the new king, and will marry his daughter to further cement the claim. Later on, it becomes clear that the princess has absolutely no problems with this arrangement and is actively assisting him. This king then goes on to rebuild the kingdom's dying economy and begins laying down the foundations for a stronger military force, all the while he is communicating with his subjects about what state of kingdom is like and furthermore offers them solutions to the food crisis in a fun and entertaining manner...and this is after he sent out a call for talents of all kinds to display what they can do, incidentally giving some of those that entered the contests exposure to anyone interested in their talents.
Now after seeing the Head of the Navy, the one everyone agrees is a strategic genius, side with the new king, he blusters and sides with the pretend traitor, who was serving as a gathering point for corrupt nobles, because of Friendship. There was no forethought going into this regarding penalties of being a traitor to the throne, no thought about how his actions would affect his people and loyal soldiers and especially his daughter, and unlike George, there wasn't even greater strategic plan underlying his decision. Only, "Duke George is my friend and I'm siding with him."
Would you trust someone like that with something so sensitive?
