US is neither pacifist nor docile. Definitely more intelligent than India. Worry about India dude, specifically when comes to securing its interests- every insult to India has gone unanswered in last 20 years except recent strikes in Pakistan. (I am a fan of Modi)- finally an Indian politician with spine.
Also, India is full with people like you who on one side want India to be aggressive about it’s foreign policy, but when seeing the effects of those policies, hide behind criticism and prejudice. There is always a cost to be aggressor and US has paid it- but it does not take away the American willingness to be aggressive and to do what’s needed to be done. Iran is next and you will see that soon.
Come back to me when you can punish a single mastermind of Mumbai attacks. Till then keep your fantasies to yourself.
