Psychological War

It's very interesting reading the different accounts of individuals affected by imperialism-induced war. Not that it can compare to the colonized country's state, but are there negative long-term effects to the colonizing country? Could one country's imperialism in one country be enough to shake the populous of its own? One French girl, who's father was a torturer, had psychological results due to the guilt and embarrassment she felt for her fathers actions--but she had some first hand experience herself. The population of effect peoples is probably too small to have enough weight in the home country.

It seems, based on Fanon's patient accounts, that the psychological effects of war and imperialism push and exhaust patients to look past the liberation of their cause and just hope for mental rest. How can a colonized nation paralyzed by war move past to achieve liberation?
