Is Obama right over Iraq?
The Obama doctrine, set out at West Point, appears to be in tatters as Iraq falls apart. The critics have been quick to point to what's happening there as another sign of the weakness of his foreign policy.
But there is another way of looking at it. That he's right.
Here's the case for the prosecution. That in his haste to proclaim the war over, he pulled US troops before the Iraqi government was ready to go it alone.
He failed to reach a meaningful military deal with the country. He's taken his eye off the ball, done little to encourage civil society and a more balanced political solution. He has not led the world in identifying a looming crisis and crafting a coherent response.
The Obama doctrine says the US will only go to war if its vital interests or those of its allies are threatened.

Mark Mardell: Virginia Tea Party victory a harbinger
What Mark Twain really said was, "It has been reported that I was seriously ill - it was another man; dying - it was another man; dead - the other man again."
So, as I have been saying for many months, the death of the Tea Party has been exaggerated by those who rather hoped it was staggering towards extinction.

Taliban tout Sgt Bowe Bergdahl prisoner swap 'victory'
In the most striking moments of the long, triumphant Taliban video, Sgt Bowe Bergdahl blinks rapidly, looking rather dazed.

Obama in Europe shows the limits of US power
Whether he likes it or not, President Barack Obama's trip to Europe will be about Ukraine, Vladimir Putin and American power.
He may not stoop to pick up the geopolitical gauntlet thrown down by the Russian leader. He probably will set out new red lines - warning Mr Putin not to mess with Nato.
CO2 emissions: Obama's war of choice
There are, they say, wars of choice and wars of necessity. President Obama has embarked on a war of choice - one that will delight some Democrats but could cost others dearly.
Republicans claim it is a "war on coal", a toxic mix of executive overreach and dogma.
Is US foreign policy 'vacuous, vapid and weak'?
Under the blazing South Carolina sun on Parris Island, young men and women march in smart formation to the distinct rat-a-tat of the drums and the ump-pah of trombones of a military band.
These are the Marine Corps' newest graduates, the freshest faces in the most powerful fighting force the world has ever known, the United States military.
Mark Mardell: Tea Party loses battle, if not the war
The Republican establishment in Washington is letting out a long sigh of relief - its standard bearers survived a concerted assault by the Tea Party.
Last night's primary elections will be taken as a significant turning point, the day the establishment fought back and won against conservative radicals.
Chinese hacking: US calls out '21st Century burglary'
"Enough is enough," said Attorney General Eric Holder.
The US government is baring its teeth, showing a new aggression towards Chinese hackers and what the authorities here call "21st Century burglary".
