Unfortunately it would be just an emotional reaction. You may even drop a nuke on Raqqa, perhaps 2,000 ISIS will get killed, while 50,000 civilians will be dead too and this will create another 10,000 ISIS memebrs. Western countries also launch some ceremonial 'heavy' air raids on Raqqa after each terror attack.
This is NOT the way to defeat ISIS. It actually takes years to defeat it completely, when a generation is not raised with hate and dogmatism, when many Sunni Muslims are not prone to joining ISIS with smallest excuses, when Muslims ALL find ISIS and similar groups' ideology as a dark and vile one. But that's not the case now.
RIP to the deceased and may the injured recover soon.
