In the article the author argues that discrimination of many people and nation by European colonialism through some last centuries was the reason of innumerable crimes and sufferance all over the world. That process he compares with a great destructive wave of tsunami. Today we can observe the opposite and negative reaction to those injustice in the past, namely it is the process of coming back wave of tsunami. i.e. coming back wave of revenge. Its source is quite deep and complicated because of enlarged areas of the world poverty. To be more clear it is impossible to avoid that revenge unless rich countries decide to replace military and economic domination by immense help. Better make medical services, schools and agriculture in miserable countries than guns and rockets.
