The difference between ISIS and Iraq 2003 is that Iraq had no intention of attacking us. ISIS lonewolves and terrorist cells will continues to attack Western civilians, and we have to strike back. They truly believe they are in the endtimes. That being said, Arab nations such as Egypt and Jordan must participate in a ground war as well.
Do we actually know of any plots hatched by IS itself, as opposed to just "IS inspired lone wolves" who do their own thing in the name of IS?
And if this is really the issue, then why not also do a ground invasion of Yemen in order to take out AQAP?
