"It has been exceptionally rare for major powers to intervene militarily for predominantly humanitarian reasons. One example was the US-led Kosovo campaign in 1999, and another was Britain’s dispatch of troops to Sierra Leone in 2000 to end the brutal civil war there. Both were successes, but came only after years of killings that gradually built up the political will to do something.Critics argue that we are inconsistent, even hypocritical, in our military interventions. After all, we intervened promptly this time in a country with oil, while we have largely ignored Ivory Coast and Darfur — not to mention Yemen, Syria and Bahrain. We may as well plead guilty. We are inconsistent. There’s no doubt that we cherry-pick our humanitarian interventions. But just because we allowed Rwandans or Darfuris to be massacred, does it really follow that to be consistent we should allow Libyans to be massacred as well? Isn’t it better to inconsistently save some lives than to consistently save none?"
