These studies are great (I grabbed a bunch last year in Leavenworth when I spoke at a conference). Sierra Leone shows what a modest military intervention can achieve if well-designed and well-timed. About 100 British marines accomplished a lot.

Point being: only bad interventions must necessarily be huge ones. Good ones can come in a variety of sizes and public-private mixes.

Look at Kurdish Iraq for example: few troops, heavy tilt to private sector.
