Thank you Keith for conceding that the incursion was a violation of Pakistani sovereignty.

I must correct you on one point. I am not arguing whether the killing of ObL was morally wrong or otherwise. In my view it was an unlawful killing. It may or may not turn out to have been generally beneficial.

I am worried about the precedent it sets. If the US may (I know it can) violate the sovereignty of one of its allies, enter their territory, and kill an unarmed person there, what keeps the rest of us safe?
