Support for the war in Afghanistan has hit a new low and Obama's approval rating for handling it has declined sharply since spring, according to the most recent ABC News-Washington Post poll.
The number of Americans who said the war in Afghanistan has been worth fighting has declined from 52 percent in December to 43 percent. And Obama's approval rating for handling it, 56 percent in April, is down to 45 percent.
The Army specialist allegedly behind the intelligence breach -- Bradley Manning -- is in U.S. custody after his arrest in May outside Baghdad on charges of releasing classified information.
As national security experts examine how the breach occurred, some observers say Manning could not have acted alone.
"I do not believe private Manning had the technical expertise necessary to communicate this amount of information to the outside world without being detected and I don't believe that he operated without guidance," computer hacker Adrian Lamo told "Good Morning America."
Lamo said he was contacted in May by someone calling himself 'Bradass87' -- believed to be U.S. Army Spc. Brad Manning -- who claimed to be an Army intelligence analyst with access to classified networks that showed "incredible things, awful things ... that belong in the public domain."
Lamo turned the online conversations over to Pentagon investigators because he believed there could be potential harm if the classified information came out.
"[Manning] misused a tool that was intended to help protect, defend, save American lives and the lives of really everybody in the coalition," he told ABC News Sacramento, Calif., affiliate KXTV.
Lamo added that he'd do the same thing again -- though he claimed he's received death threats.
"There has been a backlash, as I knew there would be," Lamo told KXTV. "I didn't really expect the raw hatred, the vitriol."
But Manning, or whoever contacted Lamo, apparently made the same pitch to Wikileaks.org founder Assange.
Assange refused to confirm Manning supplied the material today, saying, "We still don't know who the source is."
If it were Manning, he added, "He's a hero."
Witnesses report the Taliban has used heat-seeking missiles against aircraft, something U.S. officials have never acknowledged, according to the documents. Secret commando raids, such as those made by the secretive Task Force 373, have been increased under the Obama administration but, despite successes, the leaks now reveal some "high-value" targets have not been there when the U.S. was striking. Instead, children have been killed in some instances.
Perhaps the most troubling aspect of the reports for U.S. officials are those that strongly suggest the ISI was double-crossing the United States. A report suggested last year that the former head of ISI was encouraging insurgents to focus their operations in Afghanistan "in exchange for the government of Pakistan's security forces turning a blind eye" to insurgents in Pakistan.
