Trump adviser John Bolton on possibly privatizing US war in Afghanistan: I'm 'always open to new ideas' Bolton said possibility of using private military contractors up to president.

President Donald Trump’s national security adviser addressed the idea of using private contractors to help fight the U.S. war in Afghanistan, saying he is "always open to new ideas."

In an exclusive interview Sunday, John Bolton responded to a question from ABC News “This Week” Co-Anchor and Chief Global Affairs Correspondent Martha Raddatz about possibly privatizing some part of what is now America’s longest war, the nearly 17-year-old conflict in Afghanistan.

“Would you consider privatizing [in Afghanistan], with using contractors instead of U.S. military? There have been some reports about that this week,” Raddatz said.

“There's always a lot of discussions,” the president's national security adviser said. “I'm always open to new ideas, but I'm not going to comment on what the thinking is. That will ultimately be the president's decision.”

According a report from NBC News Friday citing current and former administration officials, the president is showing interest in a proposal by Blackwater founder Erik Prince to hire private military contractors to support the war.

“It is not a private army," Prince told NBC News of his proposal for Afghanistan. "It is a very clear delineation of who’s in charge, OK? Afghan government working for a U.S. government official funded by the United States at a fraction of the cost we’re spending now.”

Prince, who now heads Hong Kong-based security firm Frontier Services Group, also told NBC News that Trump advisers who oppose his plan are painting "as rosy a picture as they can" of the recent U.S. efforts for peace talks with the Taliban.

Bolton told Raddatz there are “signs” conversations between the Taliban and Afghan government are “moving in the right direction.”

“We've looked at several different possibilities to get the Taliban and others directly engaged with the government of Afghanistan. There have been some signs that's moving in the right direction," Bolton said.

“I don't rule out that we'd have a change in some of the things we're doing there, but the president's view is that he'll support the government of Afghanistan in its efforts to see if the Taliban are finally ready to talk seriously,” Bolton said.

Raddatz pressed, “I feel like I've heard these arguments for 17 years, the same thing: 'The Taliban is desperate.'”

Bolton responded, “Well, what I remember over 17 years is the attack on 9/11. And I think the administration is determined that it never happen again.”

“The bottom line is the security of the United States,” he said.
