You are of course right. I just have a negative opinion on the character who indeed made several stupid decisions for which he and his country paid a huge price. Being frivolous, selfish, irresolute and vacillating can turn a not stupid person into a stupid king, in regard with the qualities that are required of a king and of a king's duties.
Seeking support among the young king's enemies would have been a quite foolish choice. Especially in the kingdom of France where all those who chose to go on a collision course with the king of France finally met defeat. The best opponents could hope was getting the king's favor or reducing the king's powers. That was in the reach of the Valois Burgundy because they were very powerful and were in fact a power on the international field. That was not in the reach of the Valois Angouleme who were far from being as powerful as the Valois Burgundy had been and who did not even have the advantage of having its principality close to a border enabling them to get foreign support.
An interesting analysis, so with his marriage to Mary Tudor, and his sister married to Charles V, how might things go with regards to the Italian wars, if indeed they still happen?
