American Hostage's Mother: US Failed Our Children

— -- The mother of an American journalist who was the first hostage beheaded by ISIS last August lashed out at the Obama administration on Saturday, saying the alleged death of Kayla Mueller on Friday was a reminder that "nothing was done" to save those in captivity.

Diane Foley, whose son James Foley was shown in an Aug. 19 ISIS video being killed by the group's spokesman "Jihad John," has spoken out before -- but Mueller's possible fate renewed her ire over what she feels was the government's inattention to the crisis.

"Kayla, along with our son and others were held for nearly two years and there were many opportunities along the way: several times when the captors reached out, several times when returning hostages brought sensitive information. And yet nothing was done to save our young Americans. So that's the part that deeply concerns me," Foley told ABC News in an interview, parts of which aired on "World News Tonight."

On Friday, ISIS claimed that Mueller, 26 -- whose name was mostly kept secret publicly because her captors had demanded a media blackout from her family in Prescott, Arizona -- was killed in a Jordanian airstrike on a building in Raqqa, Syria.

While Jordan did conduct airstrikes in Raqqa, ISIS has offered no evidence yet of her death, much less on that date or in a coalition bombing run.

Many counter-terrorism officials focused on ISIS remain deeply skeptical, while the Muellers in seclusion have signaled they do not know whether they should accept their daughter's death or not.

For much of 2013 and 2014, Diane Foley and hostage negotiators working for her family knew the likely locations of the western captives held by ISIS in Syria, even as they were moved from time to time. But the U.S. didn't launch a mission until July 3, when a squadron of operators from the elite Delta Force hit an oil refinery site near Raqqa, discovering it was a "dry hole."

Kayla Mueller had been among those held there, counter-terrorism sources have told ABC News.

"I certainly applaud the young, courageous soldiers who went on that mission. It was much too late and the intelligence obviously was poor -- it wasn't good enough for those courageous soldiers -- so they went in for nothing," Foley said.

A counter-terrorism official with knowledge of the planning and execution of the July 3 rescue operation said Diane Foley's assessment was correct.

"Washington took too long. We missed the hostages by two days. We could have had all the hostages -- all of them," the counter-terrorism official told ABC News last week, still upset over the outcome.

Since then, three American, two British, two Japanese and a Jordanian hostage have been executed in gruesome ISIS videos.

A spokesman for the National Security Council declined to address Foley's criticism directly but said the White House is conducting a review due this spring ordered by President Obama of the government's hostage policy, which generally falls under classified portions of National Security Presidential Directive-12.
