I think targeting Americans/Britons could be just to get wide spread attention than hate against any religion or nationality.

India currently is just a broken system - everybody having their bit of contribution to this whole mess including "aam aadmi" - common man who just sat quiet. Its just waste of time to get into blame game of pointing to political parties, religions, communities or anything.

India just has to get into a mass movement and fix itself. Or for the time being at least may be army should take over hoping it can't be worse.
