A very perplexing decision will be upon us. Do we back a predominately muslim country just because we have a temporary bi-lateral agreement with them in respect to hunting terrorists? Which we have quite possibly milked for all thats worth, save for UBL hisself. (a nuke may be whats needed here). Or do we side with a Hindu nation that in a purelitic fit ran into Chinas' arms after our giving them a spanking over nuclear arms proliferaion.
I believe it comes down to a question of which culture could we see ourselves fighting alongside.
My bet is on the Hindus.
Nevertheless, broad cultural affinity- or lack thereof- between any two nations, which are generally underpinned by the manner of expression of the moral/ethical values of the predominant religions practiced therein, can be a fairly accurate predictor for the durability of any particular kind of relationship between said countries. So I concur that India would appear to be the more rational, natural choice for an ally, despite their prior flirting (and that taught a good lesson to the Indians!!) with the Chinese.
PS- Even a cursory comparison of the primary religious texts of Islam and Hinduism will reveal to common sense that the latter poses no threat to anyone, whereas the former, well, 'ye shall know them by their fruits...'
