...elect to go to war and you are automatically condemned to accept the consequences.

If that means that you should not be surprised at the the consequences, that may be true enough.

If it means that the consequences are justified, it would imply that terrorism is justified in many or even in most of the circumstances in which it takes place.

I do not think that Hamas or Al Qaeda would quarrel with Teribus on that particular point, even if they might disagree on the definition of "elect to go to war" some of the time.
