At best I would expect such agreements to slow down the genocide against Gaza for a few days. Human groups have degenerated into hatred in the worst of history … since about 10k years. A genetic reproductive advantage was gained by violent victorious warrior monsters (as an example Gensis Khan is said to have had many descendants). Eventually humanity will need some type of widespread gene therapy to get rid of our band bad tendencies … i know all that is a broad oversimplification, but still.
Edit : Ooups ! i made a typo.
