The mansion in Abbottabad, Pakistan where Osama bin Laden was found and killed is at least six times the size of the typical house near it. Abbottabad is a military town, where many from the Pakistani military retire - raising questions about how Pakistani authorities could not locate and capture bin Laden themselves.

Osama bin Laden lived inside this million dollar mansion for at least nine months. Some counterterrorism experts think he was there six years, since the compound was built. The five-meter-high privacy wall is topped with razor wire. A TV satellite dish sits atop a sunroom. The mansion dwarfs neighboring houses. And it is within walking distance of a Pakistan military academy.

Former US Secretary of State Condoleezza Rice:

"Obviously, it raises some important questions, questions that really the Pakistanis need to answer, not only for us, but for themselves," she said.

Lawmakers in Washington have their own questions.

"I think Americans are asking how they could have gone undetected for that long, in that kind of environment. And does it reflect to some extent some kind of divided loyalty or complicity in some part?"

"And for all the money we've spent, how can we develop a relationship of trust with the Pakistani government, while in fact you have what I'd call a very weak president and an ISI [intelligence service], that is rogue."

Much money was spent. The United States has given Pakistan $20 billion dollars since the terrorist attacks of 2001. Analysts say Pakistan worried that money would evaporate if bin Laden were caught. Others say giving up bin Laden would be a political risk for Pakistan.

A government statement says Paksitan gave the CIA leads that helped the US identify and reach bin Laden. The Pakistan high commissioner to Britain, Wajid Shamsul Hasan:

"We pointed them out to the American intelligence and we did not allow him to run away from the place," said Wajid Shamsul Hasan.

"I think the word ally needs to not be used anymore," said Lisa Curtis.

Lisa Curtis is with The Heritage Foundation. She says Pakistan did not search hard enough for the world's most wanted terrorist.

"This should strengthen Obama's hand in convincing Pakistan to take stronger action against the terrorists that we know are still there," she said.

Pakistan-US relations were strained earlier this year when Pakistan demanded the US reduce the number of drone strikes and CIA operatives in the country. But without them, bin Laden might have not been caught.
