Hampson and Burney write their small, jaded brief (a very short article) that has no context, that is mostly opinion and lacks basic facts, and points out all the bad things in the world.   Co-authored, by the way, by a political appointee who served under George Bush (Senior).  
Adam Radwanski wrote a detailed, well-researched article on Obama (it is on my cell phone, I don't see it on the G&M website yet) that paints a much different and nuanced picture of Obama and the challenges of our time (both the good and the bad).
I would suggest everyone look at the Radwanski article as well, then if you wish to comment further below, knock yourself out.
I'm tired of reading quips from the same old, bitter, knee-jerk Con trolls.
