that perhaps prevented another Rwandan-esque massacre/human tragedy
Don't forget that through a masterstroke of spineless UK international policy combined with the usual UN corruption, 5 Airborne Brigade deployed to Rwanda in 1994 to help count the mutilated bodies and watch the Hutus and Tutsis kill a few thousands more of each other. The French actively supported the Hutus, who instigated the genocide, and the US chose to ignore it completely, so the UN sent body counters.
Nothing has changed in 14 years, the genocide has moved West a few hundred miles to another country, but the West are as powerless as ever to help because of the massive corruption and complacency at every political level.
Deploying a few hundred UK Undertakers would be more effective than sending Professional Soldiers to witness more tribal bloodletting.
