1: He literally said "...peaceful transition uhh military power." The word "to" can be more lazily pronounced as "tuhh" which can then even more lazily be pronounced as just "uhh". As someone who has lived in the south my entire life, I've heard plenty of people lazily pronounce "to" as "uhh" in this manner.

2: The phrase "peaceful transition of power" is so commonly said that to add the word "military" to it would be very strange. Any notion of the power of the military being transferred from the previous president to the new one would be inherent in the commonly said phrase "peaceful transition of power"; if that's what he meant then surely he would have just said "peaceful transition of power" instead of "peaceful transition of military power."

Conclusion: Him saying "...peaceful transition uhh military power." could have been him saying "...peaceful transition to military power." and I think it make more sense for him to have said that than him saying "...peaceful transition of military power." over the most commonly used phrase of "...peaceful transition of power."
