No you heard:

• Peaceful transition-ta military power.

the ta is dialectic.

The alternative would have been:

• Peaceful transition-a military power.

where the "n" blends in with a soft transition. BUT the -a is not commonly used in this phrase construction.

It resembles the "ta" more. But he's also wearing a mask.

It's also WIERD to reference the transition of power as "military" power.

If you have a phone, put it next to your ear. He says "peaceful transition ta military power". The ta sounds like of.

i heard "to"
