My 2 cents: Huge mistake.
You want worldwide outrage till the end of time? Then nuke medina and you will have it.
You will also have terror on a scale never before imagined.
Coincidentally, the identical technique used by the Muslim Mass Murderers:
There are too many of us, so you might as well give up now.
How much more mayhem and murder will it take to make that clear?
Personally my response is the one finger salute and "bring it on", mohamid.
