It is not important to have killed a senior ISIS leader. They just stuff someone else in the job immediately. Organizations like ISIS are located throughout the planet. The surgical strikes and limited attacks aren't going to solve the problem; just drain resources, which they are counting upon.
The west needs to wake up and think of Islam as one would think of a dandelion plant. Isis, Taliban, Al Shabab, Boko Haram, et cetera, are like the seeds one sees floating through the air when the wind blows on a dandelion. They plant themselves in new locations, sprout and continue to spread. To kill a weed, you have to kill the root and the root in this case is, the Koran. To kill the Koran, you kill all of Islam. No seeds. No weeds. No followers. No threat.
