James Foley's siblings have stated that the U.S. could have done more to save him.

Just days after the death of their brother, Michael and Katie Foley sat down with Katie Couric in an interview with Yahoo! News. Michael, 38, told Couric that the U.S. should reconsider how it deals with terrorists.

"I really, really hope that in some way Jim's death pushes us to take another look at our approach, our policy, to terrorists and hostage negotiations and rethink that," Foley said. "Because if the United States is doing it one way and Europe is doing it another way, by definition it won't work."

American journalist James Foley, 40, was beheaded by the Islamic group ISIS, also known as ISIL, one week after the group's $132 million ransom request was denied. 

The U.S. does not negotiate with terrorists, however, ISIS has extorted more that $100 million from "compliant European countries" for the release of prisoners, according to Mail Online.

Foley thinks that more could have been done to save his brother even without the U.S. meeting the rebel group's ransom requests. The rebel group is now threatening to kill another American journalist, Steven Sotloff.

Foley stated: "The U.S. could have done more on behalf of the western and American hostages over there and still...you know, dealt with the broader, worldwide issues. Other nations have done that. And that's been a source of frustration for me. Take the money aside, there's more that could have been done directly on Jim's behalf and I really hope that with respect to Steven, they take some action quickly." 

In a Today Show interview, Foley's parents said that the U.S.' negotiation process was "very uneven." The Foley's anger flared after they watch the gruesome video of the beheading. The family claims they will one day forgive their son's killers.

"There's ways to do it," Michael said of rescuing the hostages. "I just feel strongly that more can be done moving forward."
