The problem is that all these bombings would actually help expand ISIS as civilians lose their dear ones/homes/livelihood due to allied bombing. Between 2014 to 2017, estimated drop in numbers of ISIS fighters was 6000 - that's about 20% drop [1]. Assuming all of them were killed, that's about 2000/year i.e. almost exactly number of airstrikes. So either it is taking one air strike to kill one terrorist or ISIS gets refueled pretty fast from disgruntled civilian population.
