For John, BLUF: Sometimes you do things you think are small potatoes and they turn out otherwise. Nothing to see here; just move along.
I sometimes wonder if killing top Da'ish Commanders just clears out the deadwood and allows talented younger folks to move up. It is a theory. On the other hand, maybe it works to reduce the overall ranks of Da'ish members. This article, from The Stars and Stripes, says that the targeted killing of Abu Hayjaa al-Tunsi resulted in 38 additional deaths, as Da'ish looked for the informants who gave away targeting information.
