Note that I said "internationally-speaking." Individual Third World countries of course have their own moral codes, but (1) they are different from country to country, so one action is unlikely to impress the "whole world" the same way, and (2) given a history of poverty and defeat, they are not very likely to stick out their necks for a moral principle even if they believe in any.

The closest thing the Third World has to a shared moral value is "anti-colonialism," but that means different things to different countries, and given that real "colonialism" died over half a century ago, is unlikely to impel them to do anything of much practical benefit to anyone else.
