F*ck France for ever trying to colonize Somali lands even if they did some minute good in some cases by some chance. But that aside, it's a beautiful sounding language and I admire French cuisine. They are by far Rome's most successful colony to date in my opinion.
On a serious note, Colonization is an alienation to the locals and a huge deal of loss for the Colonizers. I note usually the cultural impacts of this process of occupation, but in a psychological standpoint, it alienates the locals; as their norms are now outdated, they are '"indigenous", dominated, subjugated. Many will collaborate but half-heartedly, while a few will engage in active resistance and a small portion will completely assimilate, despite discriminations and rejections.
But Colonization was bound to happen as the great Industrialists of the West wanted to expand and own more lands, while the population was bigger and more asking and the Politicians ressorted to Republican Universalism of "educating the savages to the true values of Humanism, as Jules Ferry's main rhetory was).
I can agree with the idea that this occupation may create mental and physical pains, as it de-naturates with the psyché of the "Indigène". China's main focus was to avenge its humiliation during the Opium Wars (around 20 millions of people lost their lives during the Chinese civil wars).
Africans should be harvesting this energy to regain their perceptived dignity.
