How to fight them? We should instead be asking how not to create them instead.
Same applies to all the drone attacks that Obama's sanctioned since he took office. There was a case study in the ME where a village was fairly neutral towards the US until a drone strike killed a group of civilians and the entire region became insanely anti-US. Dropping bombs now just creates more enemies in the future.
We don't need case study to understand this things. All we need is common sense.
For example if one country bomb your city and one of your love ones died. What would you do? Smile and shake hands with the killers?
Exactly, problem is that nobody in government (especially in the military) has any common sense, the only way people get to that level of power is by being a ruthless psychopath. One major problem is that war has become a collosal money making industry. You've got the military industrial complex making $billions on hardware and then there's the bottom feeding oil corporations sniffing around for more resources to plunder.
