Former President George W. Bush joined a chorus of U.S. officials calling any leaks of sensitive government information “very damaging,” telling a forum at Facebook headquarters that WikiLeaks' recent release of 250,000 documents may significantly hurt Washington's image abroad.

"It's going to be very hard to keep the trust of foreign leaders," the nation's 43rd president said of the documents on issues ranging from Iran to Honduras to Turkey. "If you have a conversation with a foreign leader and it ends up in a newspaper, you don't like it. I didn't like it," CNN cited him as saying.
