Does the strategy of solo diplo depend upon our ability to convert the civs on the other continent to Hinduism?
I do not have the experience to know the likelihood of a successful outcome with this strategy.

In some ways, it seems as though it may be the fastest way to go? But I do not have a picture in my mind of how it will go. I think we should consider this a bit more perhaps.
EDIT - I also do not really understand the risks versus the reward of trying this. To win, perhaps we need to stick our necks out a bit and see if the axe falls, or not?
We have worked quite hard, and I think successfully, at getting to the PA. I do not wish this objective to blind us into thinking it is the only way. Can we talk some more about this possible path to victory?
