Did the Pakistani Government itself have the Marriott Bomb go off?

Inquiring minds want to know, for the timing and circumstances are deeply suspicious.
1. The bombing comes at a time when the US is increasingly seeing Pakistan as a (if not THE) perpetrator of Terrorism, what with their UAVs going and bombing bits of the countryside. In one masterstroke, Pakistan has gone from being a perpetrator to a victim.

2. How did a vehicle, with over a metric ton of explosives get through the MArriot's security cordon? Go to any Five Star property and they search your vehicle bare. There is no way the vehicle could have gone through unless the Hotel had been told to let it through. I can see the "nudge-nudge, wink-wink" happening between Zardari and the ISI.

3. One mega bomb in a hotel is a very poor use of 1 metric ton of explosives. If the intent was REALLY to cause terror, then 20 bombs of 50 kgs would have wreaked more havoc. That would have killed at least 20*20=400 people.

The whole incident seems tailor-made to make a point and not really cause terror.
Its worked wonderfully, the desi ELM is having wet dreams again ... "awww, they're victims too! Just like us! Let's do a candle light vigil at Wagah"

One needs to learn from these guys how to convince the world of your victimhood. And then make demands for candy bars. Or f-16s. The BJP is Karnataka needs to learn from them pronto. Hindus, despite being victims, have lost the perception war against the Christist machine there. They just dont know how to portray themselves as victims.
