Answer:
International humanitarian aid is one of the few situations in which the technological, human and financial resources of diverse countries are equalized. Practically any country may help another with humanitarian aid operations and resources and it has happened that powerful nations, in a moment of need after a disaster, have received help from nations they considered previously as too small or poor.
It is also when mankind goes beyond beliefs and politics and helps other communities seeing them as just fellow human beings in suffering and need.
