The view from two neighbors.

The NYTimes has a decent summary (as of yesterday) of the Indian suspicions that the attackers in Mumbai were, to some degree, tied to or based in Pakistan.

Also of interest, last week's NYTimes piece on the paranoia in Pakistan over India.

Neither piece has anything truly concrete, but together they hint at the suspicions that plague the India-Pakistan relationship, and highlight the difficulty the US will have in taming Pakistan's violent factions. Pakistan keeps those groups as policy, as a lever against India, both in Kashmir/India, and in Afghanistan as a bulwark against Indian influence.

(And, Robert Fisk writes a near epitaph of Afghanistan.)
