Sure......mythical stories of Jaichand and Pritviraj is what passes for history in pdf
At the time Ghauri's invation there was NO internet to tell those kings what a great danger islamic invasion was to do to India. Nor did they have the hind sight of a 1000 years of history to advice them.
All they knew was an barbaric king invaded and they used that to settle they own political ambition. The way it happens anywhere in the world. LOL.
That is pretty much the same way it played out with the British too. No one expected a bunch of traders to take over the whole world and establish the greatest empire known to mankind.
There was NO betrayal of Hinduism since no one knew Hinduism was in danger. Before the islamic invasion NO one in India had experienced ANYTHING similar to it.
The only thing close to it is the Christian invasion of India and the Sikhs in US supporting that invasion. Now that is a betrayal and cowardice worth talking about. Think about that.
