Labster, clinical insanity and criminal insanity are two distinctly different things.
The first is a diagnosis that is specifically about how able you are at estimating reality's most likely outcomes and handling those outcomes. The judicial system does not touch these matters except for those cases where the patient is a threat to themselves and/or others, and in that case it's solely to ensure the proper mental healthcare is provided.
The second is an estimation of your ability to discern right from wrong. The fact that terrorists can define some form of right and wrong, no matter how divorced from anybody else's, rather than being incapable of discerning right from wrong makes criminal insanity an unlikely to be successful defense. If it were a successful defense, check the previous paragraph.
