The United States is doing everything they possibly can to get India to not attack.
We outta be minding our own business. I am sick of all of this "pot calling the kettle black" crap. If Congress had been hit by terrorist sponsored by Mexico or Candada is their little doubt that we would attack? This is the same as our poo pooing when the Russians went back into Checkneya. I say we let India do whatever India feels is necessary to protect its interests.
Of course not. But there's no evidence that the attack on India was sponsored by Pakistan.
We've seen some evidence that Pakistanis are responsible but no evidence that it was an action approved by the Pakistan government.
In fact, it is extremely unlikely that the government would choose to do such a thing. The Parliament attack wouldn't have advanced any of Pakistan's goals and it certainly would have jeopardized everything that Musharraf has done in aligning Pakistan with America on the war on terrorism.
More likely, it was an attack by a group aligned with al-Qaida, in an effort to provoke a war against Pakistan. That would require Musharraf to pull his troops away from the Afghan border and made it easier for bin Laden and his followers to flee into Pakistan.
If India were rational, they would provide whatever evidence they have to Pakistan so that they could arrest anyone responsible. Instead, India is playing right into the hands of the terrorists.
