Obama's Libyan mission creep?
The worries about what the mission is in Libya are growing.
Some of it is mischief-making by media looking for a story or President Barack Obama's opponents looking for an easy hit.
There is, after all, no contradiction in the White House position that the UN-sanctioned military mission is restricted to protecting civilians but that the longer-term, broader political aim is to remove Col Muammar Gaddafi.
What is left unsaid is that presumably the man giving the orders to kill civilians is Col Gaddafi. Getting rid of him would protect civilians. QED.
Unknown but worrying everyone: what happens if there is an uncomfortable stalemate splitting the country, with Col Gaddafi still in charge around Tripoli and the rebels in control in the east?
But the latest concerns are over the read-out of a conversation between the US president and the prime minister of Turkey in which they agreed their shared goal in Libya was "installing a democratic system that respects the people's will".
The man in charge of Operation Odyssey Dawn, Adm Samuel Locklear, has just given a briefing saying the no-fly zone is now in place.
He was asked why it seemed air cover was being given to rebels attacking Col Gaddafi's forces.
After all, that has little to do with protecting civilians, if both sides are fighting.
"Great question" he replied.
The answer was the president had demanded that Libyan government forces retreat from Ajdabiya, Misrata and Zawiya. They had to restore gas, electricity and water and allow humanitarian aid into those towns.
Mission creep or not, that is a pretty high bar to set.
