The Jewish nation is meant to bring blessing upon all nations and societies. This was promised to all three patriarchs. (See 1:6 above.) Thus, the more resources the Jewish people have, the greater their mitzva to aid other nations. And the closer in spirit a nation is to the Jewish people, the greater the obligation.
As we have seen, the highest level of tzedaka is that which allows the poor to be self-sufficient. Similarly, aiding other nations should primarily involve helping them develop their own economy in all areas, including agriculture, manufacturing, education, and healthcare.
