Hi, Raoul.

This is not just about the Brits, who've sent countless military expeditionary forces to Africa when
trouble broke out over the past 200 years; or the French who've repeatedly sent their legionnaires to their 'former colonies' to quash troubles since 1960.
Belgium has had to deal with its own
African mess every twenty-thirty years or so. It sent paratroopers to the Congo/Zaire in 1964-65, and again in 1978.
America is now getting involved
more often, sending in Marines on a regular basis to Liberia, and U.S Rangers once to Somalia.

I say how long should they keep getting involved?
If there's not one troublespot & bloodshed in Africa in a particular year, its a rare 'quiet' one...
