It's the kind of "crazy" thing Trump wants to do that isn't crazy like nuking a random city or machine gunning babies. Not that it would be victimless, of course, but it would be costly and cause immense amount of problems and cause some more Very Serious People to respond.
No I'm not advocating making things worse to make them better, but if Trump is going to do something crazy and horrible that'd be a pretty funny one.
