I wouldn't expect any great arguments from someone who makes these sorts of statements:
Somebody needs to drop an atom bomb on them
Whats the problem killing a lot of terrorists concentrated in a single place?
Do I really need to explain this? Because you're going to wipe out more innocent civilians than 'terrorists'. Would it be ok to drop a nuke on the Whitehouse and wipe out half of Washington just to get rid of one of the biggest terrorists in the world? Is it ok to kill Obama's kids and any tourists in the vicinity as well in the process? No.
