Full text of the treaty: https://corum.ktb.gov.tr/EN-61494/kadesh-war-and-peace-treat...

It reads more like a military alliance agreement between kings:

1. Reamasesa-Mai-amana (King of Egypt) and Hattusili (King of Hatti) are best friends forever.

2. If a foreign country invaded one of us, the other one must send his troops.

3. Ditto with civil wars. We help each other.

4. If a high-profile person flees from Egypt or Hatti, send the bastard back.

5. If people flee from Hatti to Egypt, order them back. Do not retaliate against returnees, though. No pulling eyes/tongues. No cutting feet/ears. No destroying wives/houses/kids. Please.
