It escapes me how anyone expects the “Rock for Darfur” campaign to do any good. The conflict in Darfur is an ethnic and territorial war that isn’t based on any sort of historical misunderstanding or trivial difference. It’s also true that anything the US or any major power would do would wind up looking like Iraq. The duke of Wellington’s adage “For a great power there are no small wars” is being proven true everywhere.
So then what? Another adage “If a problem seems insolvable, enlarge it”. In this case, don’t act as a great power, or more specifically, use small powers, like private military companies, like Blackwater et. al. The money could be raised privately, they’re relatively cheap by military standards, and it wouldn’t require a massive US commitment.
There are massive legal and oversight problems involved with using PMCs, but using private means for what are essentially humanitarian efforts seems far better in every way than making a national commitment.
