Current India was born as the Socialist democratic Republic of India and had closer relations to the former USSR than the US, so naturally, the US aligned itself with Pakistan.
> Unless I am mistaken India was always a victim in aggression of its neighbors
You are mistaken. India has been an aggressor as much as a victim. Of course that's not to say the scale of aggression was like colonial powers but India is definitely not doodh-ka-dhula.
> If India put their sht (economy) together, toughened/equipped up their military I think this behavior would stop.
No. India needs to get its basics right -- Food, health care, education. The problem is /not/ the economy. If the so called 'educated' population of India actually made use of their education to participate in their democracy they would realize that economically speaking, India is not in a terribly bad state, however, the standard of life is sht as you put it, because very less focus has been put on the basics.
In the history of the world there hasn't been any single successful empire or country which got to where it was while ignoring the health, nutrition and education of its people.
