WASHINGTON — The $52.6 billion U.S. intelligence arsenal is aimed mainly at unambiguous adversaries, including al-Qaeda, North Korea and Iran. But top-secret budget documents reveal an equally intense focus on one purported ally: Pakistan.
No other nation draws as much scrutiny across so many categories of national security concern.
A 178-page summary of the U.S. intelligence community’s “black budget” shows that the U.S. has ramped up its surveillance of Pakistan’s nuclear arms, cites previously undisclosed concerns about biological and chemical sites there, and details efforts to assess the loyalties of counterterrorism sources recruited by the CIA.
Pakistan appears at the top of charts listing critical U.S. intelligence gaps. It is named as a target of newly formed analytic cells. And fears about the security of its nuclear program are so pervasive that a budget section on containing the spread of illicit weapons divides the world into two categories: Pakistan and everybody else.
The disclosures — based on documents provided to The Washington Post by former intelligence contractor Edward Snowden — expose broad new levels of U.S. distrust in an already unsteady security partnership with Pakistan. They also reveal a more expansive effort to gather intelligence on Pakistan than U.S. officials have ever disclosed.
The United States has delivered nearly $26 billion in aid to Pakistan over the past 12 years, aimed at stabilizing the country and ensuring its cooperation in counterterrorism efforts. But U.S. spy agencies appear to be shifting their attention to dangers that have emerged beyond the patch of Pakistani territory patrolled by CIA drones.
Beyond the budget files, other classified documents provided to The Washington Post expose fresh allegations of systemic human rights abuses in Pakistan. U.S. spy agencies reported that high-ranking Pakistani military and intelligence officials had been aware of — and possibly ordered — an extensive campaign of extrajudicial killings targeting militants and other adversaries.
Public disclosure of those reports, based on communications intercepts from 2010 to 2012 and other intelligence, could have forced the Obama administration to sever aid to Pakistan because of a U.S. law that prohibits military assistance to human-rights abusers. But the documents indicate administration officials decided not to press the issue in order to preserve an already frayed relationship with the Pakistanis.
The U.S. intelligence is focused on two worrisome scenarios: the possibility Pakistan’s nuclear facilities might come under attack by Islamist militants, as its army headquarters in Rawalpindi did in 2009, and even greater concern that Islamist militants might have penetrated the ranks of Pakistan’s military or intelligence services, putting them in a position to launch an insider attack or smuggle out nuclear material.
