It is hard to see how India does not blame Pakistan. The NYTimes has a story up on who is responsible:
U.S. Intelligence Focuses on Pakistani Group

WASHINGTON — American intelligence and counterterrorism officials said Friday that there was mounting evidence that a Pakistani militant group based in Kashmir, most likely Lashkar-e-Taiba, was responsible for this week’s deadly attacks in Mumbai.
The officials cautioned that they had reached no firm conclusions about who was responsible for the attacks, or how they were planned and carried out. Nevertheless, they said that evidence gathered in the past two days pointed to a role for Lashkar-e-Taiba or possibly another group based in Kashmir, Jaish-e-Muhammad, which also has a track record of attacks against India.
The officials requested anonymity in describing their current thinking and declined to discuss specifics of the intelligence that they said pointed to Kashmiri militants. In the past, the American and Indian intelligence services have used communications intercepts to tie Kashmiri militants to terrorist strikes. Indian officials may also be gleaning information from at least one captured gunman who participated in the Mumbai attacks.
The

What groups are involved in terrorism in India?
Lashkar-e-Taiba (LeT), whose name means "Army of the Pure," is a militant Islamist group operating in Pakistan as well as in Jammu and Kashmir. The group reportedly received funding from Pakistan's intelligence services until 2001, when the United States designated it an FTO and Pakistan froze its assets. LeT, which has ideological, but unconfirmed operational ties to al-Qaeda, aims to win sovereignty for Jammu and Kashmir and spread Islamic rule across India. The group is blamed for some of the most high-profile terrorist attacks in India, including the July 11, 2006 bombing of the Mumbai commuter rail.
There is also an
http://www.washingtonpost.com/wp-dyn/content/article/2008/11/28/AR2008112801718.html?hpid=topnews">article up at the Washington Post that is speculating that this attack was planned with "outside help" and points to Pakistan as a possible place where training could have been carried out. This was a very well planned attack, though it also appears that the Indian special forces in Mumbai were somewhat caught offguard. The response to this was less than stellar and the attacks went on for over 2 full days.
India is indeed in a domestic bind on this. And this is going to be a real test of US will and the ability of the old and new Administrations to work together to find a way to avoid more problems between Pakistan and India, in as far that can be done. (The US cannot solve every problem in the world either.) Pakistan PM Asif Ali Zardari is in a very tough spot. He is not a very strong leader and Pakistan was already on very shaky ground. This might destroy his government, which was already weak.
This is not good.
