America's chief envoy to Afghanistan Richard Holbrooke spoke chilling last words about the nine-year military conflict before his death Monday night.

"You've got to stop this war in Afghanistan," Holbrooke told his Pakistani surgeon before entering a 21-hour operation, the Washington Post reported.

Holbrooke was the Obama administration's special envoy to Afghanistan and Pakistan, a man whose diplomatic skills and understanding of Afghanistan and Pakistan were a valuable asset to the United States.

He died on December 13, 2010, in Washington due to complications from heart surgery.
