We do what we are doing. Air strikes and do them repeatedly and often. ISIS has to be stopped from progressing if at all possible. The other Nations in the area need to be more involved and they need to be fighting WITH us WITH their military, which isn't happening very much. We cannot shoulder this alone. We cannot afford it financially nor do we have the manpower to send in to die without a positive outcome and I am not even sure there is a positive outcome. Our going into Iraq in the first place pretty much guaranteed that positive isn't in the vocabulary. This is just my opinion.
