I visited Harrapa & Mohenjo-daro many times as I've lived there for the most of my life. I also visited nearby museums and saw the Harappan art, tools etc.

I didn't see a single art warfare ever or a soldier's sword or any war-weapon like thing at all. I've been reading about Indus civilisation since I was 10 but in almost all the time, I came to conclusion that Indus Civilisation was one of the most peaceful era of all that area (I'm not comparing that time with now but relative to other parts of the world at that time).

It is very unfortunate that India & Pakistan has most of the cities as unplanned, dirty & polluted even though they have some of the most fascinated civilisation buried behind their backyard.
