NOT SO PEACEFUL: A new book claims US President Barack Obama boasted he was "really good at killing people" while discussing drone strikes.

This will not go over well for the 2009 Nobel Peace Prize winner.

According to the new book Double Down, in which journalists Mark Halperin and John Heilemann chronicle the 2012 presidential election, President Barack Obama told his aides that he's "really good at killing people" while discussing drone strikes.

Peter Hamby of The Washington Post reported the nugget in his review of the book.

The claim by the commander-in-chief is as indisputable as it is grim.

Obama oversaw the 2009 surge in Afghanistan, 145 Predator drone strikes in NATO's 2011 Libya operations, the May 2012 raid that killed Osama bin Laden, and drone strikes that killed leader of the Pakistani Taliban leader and a senior member of the Somali-based militant group al-Shabab this week.

His administration also expanded the drone war: There have been 326 drone strikes in Pakistan, 93 in Yemen, and several in Somalia, compared to a total of 52 under George Bush.

Two of those strikes killed American-born al Qaeda propagandist Anwar al-Awlaki and his American-born 16-year-old son within two weeks.

Under Obama US drone operators began practising "signature strikes", a tactic in which targets are chosen based on patterns of suspicious behaviour and the identities of those to be killed aren't necessarily known. (The administration counts all "military-age males" in a strike zone as combatants.)

Furthermore, the disturbing trend of the "double tap" - bombing the same place in quick succession and often hitting first responders - has become common practice.

Needless to say, a lot of innocent people have been killed.

Obama has also embraced the expansion of capture/kill missions by Joint Special Operations Command (JSOC) after it developed into the primary counterterrorism tool of the Bush administration.

One JSOC operator told investigative journalist Jeremy Scahill, author of Dirty Wars: The World Is A Battlefield, that operations became "harder, faster, quicker with the full support of the White House" under Obama.

Scahill, who also made a Dirty Wars documentary, told NBC News that Obama will "go down in history as the president who legitimised and systematised a process by which the United States asserts the right to conduct assassination operations around the world".

So it is true that President Obama is "really good at killing people", but he has demonstrated that is not necessarily noble.
