no, america did help india during the 1962 war. but that has nothing to do with the nuclear deal. this deal has to be decided on its own merits.
we cannot blame the usa if it tries to contain us - that is part and parcel of geopolitics - if you (india/indians) are an idiot who is to blame! we have to be smart enough to get what we want without yielding too much. we should get more than we give.
