Pakistani officials have said Saturday’s ceasefire with India reestablished deterrence. But New Delhi insists the rules of engagement have irrevocably changed.

Foreign policy hawks sometimes argue that America should be the "world's policeman" (not to mention the world's judge, jury, and executioner). But with India and Pakistan, the United States is more like a referee, respected by both sides. That's a role the U.S. could play everywhere.

A day after a ceasefire was reached, India says its strikes into the Pakistani-held part of Kashmir and Pakistan last week killed more than 100 militants.
