As Pakistan cries foul over the U.S. raid on Usama bin Laden's compound, President Obama could once again be forced to decide whether to go over the Pakistanis' heads -- or, under their radars -- to capture or kill another high-value terror target.
Evidence from the scene where bin Laden died -- described as the largest intelligence find ever from a senior terror leader -- could lead the United States to other terrorists on Pakistani soil.
With analysts combing through the files for clues on the whereabouts of Al Qaeda's Ayman al-Zawahiri or Taliban chief Mullah Omar, some are calling on Obama to strike while Al Qaeda and its allies are staggering.
"We have no right to keep our troops on the defense dying, when we know where some of the highest-ranking people in the Taliban are," Bing West, former assistant defense secretary, told Fox News on Monday.
Former CIA Director Michael Hayden said that if the U.S. gets bin Laden's deputy -- presumed to be al-Zawahiri -- in its sights, "the same calculus" that was used on bin Laden should apply.
But if high-value terrorists are discovered to be in Pakistan, Obama could be forced to order a strike on that territory, and the thought already has Pakistani leaders fuming.
Pakistani Prime Minister Yousuf Raza Gilani defended his country in an address Monday, suggesting that while Pakistan is relieved bin Laden is dead, the U.S. had better not try another raid like that without first informing the government in Islamabad.
He said his country would not relent in rooting out terrorists, but warned any "overt or covert" attack against its assets would be met with a "matching response."
"Pakistan reserves the right to retaliate with full force. No one should underestimate the resolve and capability of our nation and armed forces to defend our sacred homeland," he said.
One senior Pakistani government source told The Telegraph newspaper the country would act if there is another "violation" of its air space. "We'll take appropriate action if any further violation takes place. We will defend our air space by any means we have," the source is quoted saying.
Husain Haqqani, Pakistan's ambassador to the U.S., also told "This Week" that the Pakistani government wants to continue "joint operations," but is concerned about the nature of the raid last weekend.
"Nobody said that we didn't want Usama bin Laden taken out. What we are offended by is the violation of our sovereignty," he said. "Now, we've heard the American explanation. But at the same time, try and put yourself in the position of a Pakistani leader who has to go to votes from the same people who will turn around and say, 'You know what? You can't protect this country from American helicopters coming in.'"
He said America "has a selling job to do in Pakistan" to convince its people the U.S. is their "ally."
So far, the White House is not pushing back on these calls.
U.S. officials say the burden is on Pakistan to take action, particularly considering the billions in U.S. aid going toward Pakistan, but barring that, the United States will act.
The president reserves the right to enter Pakistani territory to act against terror suspects if Pakistan will not, White House Press Secretary Jay Carney said last week.
National Security Adviser Tom Donilon told ABC's "This Week" that another unilateral stealth raid would "depend on the operation" and the risk involved.
Obama, in an interview with CBS' "60 Minutes," confirmed that he did not inform Pakistani officials of the raid in advance, though he praised Pakistan's cooperation considering "we've been able to kill more terrorists on Pakistani soil than just about any place else."
However, Obama also questioned whether anybody inside the Pakistani government might have known about bin Laden's location all along.
"We were surprised that he could maintain a compound like that for that long without there being a tip-off," Obama said. "We think that there had to be some sort of support network for bin Laden inside of Pakistan. But we don't know who or what that support network was. We don't know whether there might have been some people inside of government, people outside of government, and that's something that we have to investigate and, more importantly, the Pakistani government has to investigate."
