Acceptance

 I read something somewhere a long ago about how America celebrates the individual, Europe celebrates society, and India celebrates infinity. While all humans need all these dimensions, different cultures and civilizations prioritize and weight the different dimensions differently.

Thus the idea of some "universal values" that can be imposed across the world, that any society has moral monopoly, and worse, a policing force can monitor values across the world and offer judgements is naive at best and dangerous at worst.

Like individuals, all societies and countries can freely cooperate and work on common and mutually beneficial issues - trade, peace, science, education, etc, and exchange cultures and values freely. But should stay away from judging one and another's values or priorities or trying to homogenize values and culture. Unconditional acceptance of difference is essential.
