Operational partnerships between two organisations are a practical approach to humanitarian responses. MSF considers such partnerships when the objective it is pursuing in a country is similar to that of an existing national organisation, and when there is potential for synergy between these two entities. I would like to take a bit of a detour by looking at an experience that is in some ways similar: when Che Guevara tried to lead the revolution in Congo - Zaire by supporting the organisation of the guerrilla movement in the east of the country.
