Running an imperial empire is the opposite of doing charity, with the primary aim to capture resources including slaves who would be used to extend the empire. Most colonial powers were brutal. The British shared brutality and but added cunning manipulation. The worst examples were the Spaniards in Latin America and the Portuguese and Dutch in Africa. A “more human face” (if that term is appropriate at all) was put on only after the huge global waves of independence and de-colonisation after WWII.
Now, the various courts of international justice seem to be more open. Former colonized and tortured people may sue imperialists for infringement or war crime, and Palestine can do the same against Israel for illegal occupation. It is a welcome opportunity.
The test however would be severe. A test of conscience versus power! Don't expect concrete results. But as RT's comment (second link above) so aptly summarized, it at least has changed the international discourse. People's increased awareness outside their narrow, daily and myopic confines could accumulate to become a torrent, then a river, and later a big lake or sea. Who knows?
